Con frecuencia, a la tecnología le lleva muchos años abrirse paso del laboratorio a los hogares de la gente común. Sin embargo, en el caso de la tecnología Quantum Dot con la que cuentan los televisores Samsung QLED, sólo transcurrieron cerca de 30 años para que esto sucediera. Parece mucho tiempo, pero es realmente poco si no conocemos los antecedentes históricos.
En realidad, la historia de los puntos cuánticos no es tan breve. Se remonta a muchos años atrás, hasta la creación de las ventanas de vitrales — en el siglo I d.C. Es así que los humanos hemos estado aprovechando el poder de las nanopartículas — elemento central de los puntos cuánticos que acciona las imágenes sorprendentes del televisor QLED — durante mucho, pero mucho tiempo. Retrocedamos y veamos uno de los ejemplos más antiguos: las majestuosas ventanas de vitrales que datan del siglo I d.C.
¿Cómo funcionan los vitrales?
Los vitrales han existido por más de 1000 años— ¡definitivamente mucho más que el televisor QLED! En especial, los vitrales se usaban como medio de expresión artística, que se encontraba comúnmente en las iglesias europeas, durante la Edad Media. Los artistas medievales que incursionaban en la alquimia mezclaban el cloruro de oro y plata con vidrio fundido, para crear tintes rojos y amarillos que brillaban espectacularmente con la luz del sol. Cuando la luz tocaba el vitral, las nanopartículas de cloruro actuaban como puntos cuánticos, reflejando una magnífica variedad de luces rojas y amarillas en esa zona del espectro de colores.
Entonces, ¿qué tiene que ver eso con el televisor QLED?
Bueno, las creaciones sensacionales de vitrales que se encuentran en las catedrales europeas, son uno de los primeros ejemplos de la aplicación de nanopartículas similares a los puntos cuánticos por artistas humanos. Los óxidos y cloruros metálicos que se encuentran en los vitrales reaccionan con la luz de una manera similar a la de los puntos cuánticos. 1 Dichas nanopartículas tomaron un papel fundamental en la creación del fascinante efecto de estas obras clásicas de arte. Y las mismas nanopartículas — aunque mejoradas — se encuentran en las pantallas de los televisores QLED, brindando las imágenes vívidas con las que la nueva línea de Samsung está siendo reconocida.
Cómo trabajan los puntos cuánticos y cuáles son sus efectos
Mucho después de que los artistas alquimistas medievales descubrieran el método de incorporar químicamente cloruros en el vidrio, los científicos modernos empezaron a descubrir un fenómeno relacionado, casi por accidente. Al fracturar materiales con propiedades semiconductoras en partículas nanométricas — sólo ligeramente mayores que las moléculas de agua — se descubrieron otras propiedades interesantes. El tamaño ajustado de las partículas afecta el color de la emisión de luz, como resultado del cambio en la energía de banda prohibida. De este modo, al controlar el tamaño de un punto cuántico con incrementos diminutos, el espectro de colores puede expresarse en forma más plena y pura.
¿No es sorprendente que el proceso para controlar las nanopartículas para que produzcan colores asombrosos se haya refinado tanto, que ahora podamos encontrar puntos cuánticos en un televisor moderno? Hoy podemos apreciar imágenes impresionantes gracias a los puntos cuánticos de los televisores QLED, tanto como en las increíbles luces de los paneles de vitrales en las catedrales más importantes del mundo.

The voice continued. The three girls Yan, Yun, and Yu instinctively looked at Zu an, the monster he met in Yushan just now, at that time he also Finding Relief With Thc Free 21518 Cbd Gummies Anxiety Solutions Fsqfq called the other person , could it be this Does the you mentioned look like a tiger, with fur several feet long, wild boar s fangs in its mouth, and a tail several feet long Zaun briefly described the monster he just saw.
Prince Jinwu looked back three times at every step, and was really reluctant to lose the divine weapon, the Scorching Sun Bow.Meet the elders The second prince s eyes burst out with excitement.
Originally, the servants of the Sang family planned to resist, but when they heard of such a serious crime, the other party represented Jing Zhaoyin and came here under orders, so no one dared to act rashly.Yan Xuehen didn t feel annoyed when she heard her sarcasm, she naturally knew that she couldn t live here forever.
It s just that this will make the next generation of Klife Cbd Gummies Reviews Benefits And Buyer Opinions 5619 ordinary people suffer.Wait, Xi He seemed to have used the word mortal world just now, could it be that she is already a fairy At this time, Xihe continued When the golden rooster on Taogu Mountain crows, the rock pheasants in famous mountains and rivers all over the world also crow.
Go to the fairy world, and be separated from Yi Tianren forever.Seeing this scene, the people in Za an were amazed.
But Yun Jianyue and Yan Xuehen frowned. With the cultivation base of their great masters, they had already managed to remember it with their photographic memory.Hearing this, Wu Liang hastily persuaded him Your Majesty, before we untied the seals of Taotie and Chaos, there were ten days of volleying in the air, and the terrifying breath appeared in the world, etc.
In the end, he jumped the wall in a hurry and used his power in the capital.Yan Xuehen replied Didn t you boast that your charm skills are unparalleled in the world, and I don t know how to play charm skills, so naturally I can t play.
So he ran all kinds of magical skills crazily, and began to absorb the vitality of the surrounding heaven and earth, the primordial energy, and even the remaining power of the dragon veins, and he could absorb whatever he could.There was a look of struggle on his face, but he still took out a mirror and a set of rouge and gouache from the storage bag.
Those characters that the person described before feel that they can ascend at every turn.Before, she had been thinking day and night about how to unravel her relationship with Zaan, but at this moment, she felt a little inexplicably terrified.
Noticing the gaze of the First Elder, the Second Prince s heart tightened, and he quickly explained The First Elder Mingjian, it was not me who killed the brothers, but the prince.Now you should undo the puppet curse seal on him as agreed He Yunjianyue also hurriedly looked at Shun s phantom, especially Natures Vitality Cbd Gummies Benefits 951 Ingredients And Uses Yan Xuehen was a little ashamed, she was not as attentive to Zu an as Yu Yanluo.
If it was really done there, it would be a matter of blatant rebellion, and the consequences would be disastrous.Us Qiu Hong was stunned with tears. Yun Jianyue realized that she had made a slip of the tongue, and immediately explained We love mother and daughter, and your business is of course mine.
After speaking, she turned around and left. The cultivation base of the original grand master could The Benefits And Uses Of Serene Leaf 77975 Cbd Gummies For A Healthier Lifestyle Idhti disappear from the field of vision almost instantly, but for some reason, she walked very slowly, as if she didn t realize that she was also a little bit reluctant.The speed of Hot Wheels was much faster than his own flying.
But when it comes to Damanman s interests, how can Zaan talk to them about this Isn t this just an unwarranted crime I think there are always some people in this world who keep their mouths open and silent about benevolence, morality, and concern for the country and the people.Not long after returning to the room, Wang Bolin Cbd Gummies For Daytime A Natural Solution For Anxiety 79130 Stress And Wellness came to him Lord Zu, should we set off for Zishan as soon as possible and finish the errands assigned by the emperor For a few days, I wanted to find Yan Xuehen and Chu Chuyan, but now that the beauties Finding The Best Plus Cbd Gummies For Stress Relief And Overall Well 19629 have gone away, it s meaningless for him to stay here, and he still has to intrigue between the local officials and King Yan, so he simply nodded Okay, pass the order down Get ready to go Yes Wang Bolin was overjoyed, it seems that Fekkai Cbd Scalp Calming Reviews A Comprehensive Guide To Soothing And 48380 Nourishing Your Scalp Bvwuw Master Zu is still a serious person, not the kind of old fashioned person who only likes to flatter horses and officials, hum, that kid Zhang Zijiang will never flatter, when he meets such a pragmatic person Leader, isn t it inferior to me Next, Zuan went to inform Xie Daoyun, but seeing her sitting at the desk and drawing something, he couldn t help laughing and said, Sister Ling er is really hardworking, she spends any free time practicing talismans here.
said. You want to kill me Zaun looked indifferent. Congratulations, you got the answer right. By the way, I forgot to introduce you.Not only did you complete Yi s heroic journey, but you were also recognized by the artifact.
This time against the Earth Immortal, he didn t know how effective these abilities would be against the Earth Immortal, so he simply Best 0913 Rest Cbd Gummies For Sleep And Relaxation used them all, pulling the ridicule to the extreme.
The other party said from the beginning that he was going to lose There was a cold killing intent in his eyes.What, he is the mad god Is he really here The people around quickly backed away in horror, and at the same time looked at each one carefully.
This is the gorgeous dividing line Novel users please remind Please pay attention to rest your eyes when reading for a long time.The Eighth Elder s territory naturally also got news, Fifth Brother s mansion was attacked Fifth brother sent a signal for help Who moved the hand They were stunned, and then the Eighth Elder gasped, could it be related to Lin Xuan Let s go and have a look.
Well, you go to rest first, and someone will take you to the assessment later.But this shocked him, what kind of fruit it is, it needs too much strength.
The strength is not enough to go forward to fight, but they put all their strength Crafting Your Own Marijuana Gummies 528 A Stepbystep Recipe into the formation, and the peerless formation is opened.The other party has a movement skill comparable to that of a shadowless swan, and even faster in a straight line.
The killing intent burst out in the eyes of the Dragon Prince.That s how it is. Some people nodded and understood, while others said, but it s not easy to enter from the front.
The middle aged woman was surprised, and even Yu Yuhua Shengjun was taken aback.Those people all looked at Lin Xuan, and Qing Hong said, you must be that mad god.
The elders of the Fenglong clan, the patriarch of the blue clan, and the master of the Tiandao Palace also lowered their heads.This time it is only the avatar that fell. The real body of the other party is much stronger than the avatar.
Lin Xuan s voice made the people around him exclaim in surprise.The strength is much stronger than before. Outside, those people were waiting anxiously, especially Fu Hongye and the others, what happened But what made them relieved was that the Heaven s Punishment in the sky had slowly disappeared.
Such a person has too strong a status, far surpassing Lan Zheyu, even Bingling , can t compare to the other party, to be able to form an alliance with such a person, it is a great honor for the Blue Clan So, he is naturally happy.As expected, a star in the distance collapsed instantly under this gaze.
Not only that, but the souls of the twenty or so servants around him were instantly killed.Sun Qitian is so terrifying, what is the existence that even he is afraid of Lin Xuan and others didn t know, but they still retreated quickly.
Naluo stood up for a while, a pain appeared, the black rune between her eyebrows seemed to be drawn into a ghost head, she bit it with fangs and claws, but in an instant, it was pierced by Lin Xuan s fingers.There were cracks on his body, but he was quickly repaired by Immortality.
They all stared at Lin Xuan, but soon they couldn t laugh anymore, because Lin Xuan was already chatting with the iceberg goddess.He didn t come in, but he had the dragon sword soul in his body, which cut off that terrifying power and hid in the distance.
The toad roared, and I was so mad. Liu Yuan and the others also said that we were injured and our lives were not in danger, but it is a pity for the other brothers.When Patriarch Nalan arrived with a group of elders, he was dumbfounded.
The strength of the Nalan family is not something you can compete with.It was his only thought. However, he still underestimated this blow.
A few people really couldn t have imagined that they would all be killed on the spot in just a blink of an eye.After Bi Qi saw it, a satisfied smile appeared on her face and said Friend Daoist Lin is Finding Serenity With Serenity Garden Cbd Gummies Nearby A Comprehensive Guide 3067 Pbtrx really not simple, good, very good Speaking of which, Biqi stretched out a slender jade finger and touched Lin Haoming s wrist.
Obviously, the cultivation base of the senior is higher than them.That happened more than 800 years ago, and now it has been refined into a second Nascent Soul After hearing this, Iron Monster frowned slightly.
Lin Haoming is also happy for her, but it is a pity that Zhen Miao will soon face the impact of Yuan Ying.Lin doesn t seem to need to answer everyone, does he Lin Haoming sneered, followed the voice transmission to give You Shuang a few words, and You Shuang immediately turned around and went directly to Mrs.
Looking at this scene, Ye Chi said wrongly It doesn t matter what I do, I didn t do it.Obviously it is not easy to obtain this re created lotus Lin Haoming directly saw through the problem.
Feeling Zhao Keming was a little annoyed, and Li Feng also explained.Yan Yang looked at Lin Haoming again, and said with a smile You boy, you are not small, and you actually got together with Mr.
But the situation in the cave, at least within a thousand feet, is under the control of two people, which is enough for them.With one Yuan Condensing Pill and two Yuan Condensing Pills in hand, the chances of advancing to the Golden Pill will naturally be much greater.
when all the three color light spots gathered in one place, Lihuo Bixi suddenly opened his mouth and sprayed three color flame beams towards Zhao Keming.After traveling for a few miles, it seemed that there were still a few miles to pass through the Gangfeng area, but at this moment, Lin Haoming stopped, and at the same time, with a thought, Qingyu s protection for Shen Yan disappeared instantly.
After passing through about twenty or thirty places, a purple black flame appeared in a palace, and Wang Zhihan also showed surprise 0027 Cheap Cbd Gummies For Sleep Benefits Reviews And Guide on his face.Immediately afterwards, Qiu Yulan took out a small bottle and threw it casually.
He should have a lot of chances of victory. Listen, naturally I don t want to do it anymore.Hey, Lin, with this treasure in hand, I am invincible.
I can give you some benefits. In the future, you will be in the Izumo Continent and I will be in Shenzhu Island.At this time, Zhao Keming also glanced at the two spirit babies released by Lin Haoming, and said to himself Sure enough The spirit babies at the auction meeting were really refined into spirit baby clones by him.
Lin Haoming saw that the woman still had some affection, so he took a deep breath and said, Okay, don t cry and cry, I m here to save you.The slightly larger wild beast immediately opened its mouth, and a ball of yellow light shot directly at the iron pillar directly in front of it.
A slight impact of power will also shatter you to pieces.It was also a great consumption, but Wang Zhihan didn t want to show it in front of her.
But Lin Haoming was a little surprised, but Pan Qi smiled and shook his head and said 665 Understanding The Benefits And Effectiveness Of Reviv Cbd Gummies Friend Lin, you have made a mistake To be continued.Be careful What s the use of being careful at this moment If we don t take action against these wild beasts, will the wild beasts stop It s better to kill these wild beasts first, and then deal with this devil together After Lin Haoming finished speaking, Tieshan Immediately, he started drinking loudly.
You want to occupy my body, you really want to die Lin Xuan s voice sounded, and then white mist appeared around, and Lin Xuan s soul power also became stronger in an instant.Netizens please remind Please pay attention to rest your eyes when reading for a long time.
Firstly, the other party s methods were too terrifying, a sound of piano wounded all ten of Hemp And Cbd Gummies 57 Benefits Effects And Top Brands them.I can t wait for Nether King to be the most excited, because the breath here matches him very well.
Hearing this, the kings around were shocked, but the woman in purple sneered.In other words, the traces of the fifteen princes were completely seen by these people.
Of course, Lin Xuan did not take it lightly. He knew that the Golden Lion King, as a genius of the Zhan Clan, must be very terrifying.The gray clothed old man was terrifying, definitely not an ordinary power, and even close to peerless power.
Originally, according to the agreement, the eight princes and other elite powers were waiting silently at the entrance of the dark canyon.This is a gorgeous dividing line bsp This shot is really terrifying and makes people tremble.
It s useless, you are like ants in front of me. Today, you can t go anywhere Kill them for me With an order, the men in black around them moved quickly.The people of the Jiuli tribe are indeed not simple.
However, the other party was so calm and casual that he couldn t believe it.Even, I think it is possible to refine the saint s blood from this bone.
Seeing this scene, the trapped young man and the two women in the distance were immediately stunned.He turned thirty six times in the air, and then flew out.
Any one is enough to be worth several years, or even ten years of hard work.Could it be that there is something wrong with Seven Stars sneer.
I m afraid that even the saint child level will have to back away from such a monster.Otherwise, I m afraid these people can t bear it at all.
He was like a demon king, people couldn t look directly at him, and a destructive aura rushed towards his fist.In such a terrifying place like Jiuli, I m afraid that the peerless powers will not be able to succeed if they force their way into it.
In the booming valley, Lin Xuan was thinking about how to get the ancient sword in front of him.Afterwards, these people quickly retreated to a distance of fifty meters, and a purple pagoda appeared above their heads.
Lin Xuan was serious in his heart. These are just the stones on the edge.It can be said to be one of the powerful killing moves.
At the same time, we also need to explore more ancient ruins.An hour later, a shocking ray of light shone, a huge spiritual energy rolled, and then the ray disappeared.
On the ground, streams of blood flowed like a sea of blood, rapidly spreading towards the surroundings.But thinking about it, there should be more bad luck than good luck.
The old man was tall, with a hooked nose and piercing eyes, but his arms were broken.The Qijue sword technique is incomparable against the sky, especially the seventh sword, which is several times more powerful than the first six.
As a result, Duan Qingqing lost. Because not everyone can send out a terrifying feast of killing like Jian Shisan.
