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.

In front of me, this kind of diversion of attention and subterfuge of concepts, ah, woman, you don t know how to write Xu Yinluo.I want to go to Beijing more Blue Vibe Gummies for ED: A Detailed Review of Their Calming Effect Dk Male Enhancement and more.If you go to the capital, wouldn t I be socially dead again Well, I originally wanted to hide my identity.
Hearing the words, Jing Xin asked Before me, someone else has seen you, who is it Chai Xian shook his head I don t know him.On the other hand, Gongsun Villa is his territory, so he will trick people there first, and then he will notify Senior Xu to see how Senior makes a decision.
Chai Xing er s face changed.You are telling the truth, Chai Jianyuan may have really harmed your husband back then.He really didn t know whether to call this woman naive or stupid.
I happen to be short of a servant by my side.Miao Kait Davis Weight Loss Keto & ACV Gummies: Double the Power, Double the Results Youfang raised his head sharply, staring at Xu Qi an with a cold expression.Especially if you can t kill the opponent.Maybe someone backhandedly brainwashed him and sent him to Buddhism.
Of course, if they fight hard, their combat power can still overwhelm the Leizhou Chamber of Commerce.Or, a small team with steeds.Finding a needle in a haystack is also a way of finding people.
Her name is Liu Hongmian, and she was born in Wanhua Building, Jianzhou.The Buddhism is so powerful and there are many masters.
Without looking at Xu Qi an, he left directly.Although he was poisoned, at most it would be troublesome, and the injury would not be serious, let alone life threatening.They are the real officials of the frontier.En Sun Xuanji nodded.
In Anshen Temple, Emperor Yongxing, who had just had dinner, heard a lion s roar resembling Jiao Lei s explosion from a distance, and the sound was distorted when it reached the palace.It turned out that it was sneaky and Luo Yuheng who fell in love.
Senior He yelled, the orange cat ignored him, and glanced behind the door.After the words fell, Orange Maoan heard noises from the haystack beside her, and four figures emerged from the haystack.
Insert a sentence, app It s really good, it s worth installing, and even Android and Apple phones support it However, Gongsun Xiangyang said that the guy that the group of Qingzhou guys are looking for has a clue.When he Coffeecupcom Erectile Dysfunction El Toro Gummies for ED: Reviewing Their Impact on Men’s Sexual Health arrived in Yongzhou, he set up an ambush to capture Xu Qi an, but was injured by Luo Yuheng.
The dispute over Mahayana and Mahayana Buddhism has been deadlocked to this day.But he noticed that Mrs.Xu s eyes were aggressive, as if four words were written You trash Luo Yuheng put down the teacup, looked sideways at Xu Qi an, and said in a cold tone, Who gets out, you decide.
Behind him, all the monks roared together.clang People from all corners of the world drew out their sabers one after another and confronted the monks of Sanhua Temple.Li Lang.Chai Xing er held him back, her little hands were cold, and her tone became a little anxious, and said, It s not what you think.
But with so many priceless swords in front of us, She made a gesture of letting you pick and choose, but Meng Jingzhe didn t seem to see it.The evil spirit said loudly.The system couldn t sense the name of the evil god, and even the system thought he was incompetent.
Sixi took out five bottles.There is only one drop of blood in each bottle, and they are poured into a wine glass in front of them.However, there was an uncontrollable excitement in his expression.
I haven t seen him for three years.Monk Panshu is getting older, his face is covered with age spots and wrinkles, but his eyes are still clear, looking at him gently.The black hole blatantly collided with the beam of light, trying to swallow Xu Qi an, who had died of exhaustion, and the prisoner who had returned to the world, into the black hole.
Dabong has other backers What will it be.The leaders of the Gu tribe have speculated.The end of the way of swordsmanship is that although there are tens of thousands of people, I will go there.
From The yin and yang value of 20 The evil god s face darkened.The Mahayana Buddhists obviously saw it too.They muttered in the language of the Western Regions on their faces, with a look of suppressed joy and expectation.
Nine tailed Fox rolled his eyes and said with a smile Speaking of treasure, Xu Yinluo begged for a treasure from His Majesty on Yuren Island.This shattered the joy that had just filled their eyes.
So what The evil god was puzzled.Treat me like a three year old child again.His pupils narrowed slightly.Confucian saint s head was broken, and his body was covered with cracks.
does it include exercises Meng Jingzhe thought of the Gui Yi sword formula that the masked man used that day, nodded slightly, and said Now the soul locking lamp is on that man.As for the reason, Gu God did not say.How Do you want to fulfill the agreement Liuli Bodhisattva asked.
Bang Shenshu, who had been pounded by twelve pairs of arms again, leaned back, but did not slip back.Meng Jingzhe couldn t tell for a moment whether this was a projection of the past, or the young man was deliberately vilifying the god.
After the three of them got into the carriage, no one spoke.Was it Duke Wei who wrote the book He passed his hand to Xu Erlang.
And if the young man didn t stop Axi today, I m afraid that Axi would have died, How A Keto Diet Works Exploring How Does Apple Cider Vinegar Help U Lose Weight then what is this, did I kill me Seeing that she didn t believe it, the young man said again You have changed too much from before.This is the current status of Yunlu Academy.Occasionally, a small number of people can find an official position, but most of them are not reused and sent to corners.
but picked up the little girl, ran in the opposite direction.Du er Arhat clasped his hands together and said calmly, To me, you are just heretics.
Especially when it comes to the treatment of Confucian scholars, Buddhism actively promotes and spreads hatred.
How long are you going to fight with me here Gu Shen was indifferent, but Huang was obviously affected, and the black hole froze slightly in the air.Luo Yuheng s eyes shot out two golden lights, shining straight on The pitch black appearance brought him a thin layer of golden light.
After a blow from Fei Huan, he quickly returned, fell into the hands of Qishan Immortal, and disappeared.The giant panda turned around silently, refusing to answer this question.
Today the world is pacified, and the witch gods, Buddhas, and the territory of southern Xinjiang are Top 10 Keto Gummies Websites for Effective Weight Loss in 2025 Fda Weight Loss Drugs all owned by Dafeng.It s ridiculous that Wei Yuan is clueless, Zhao Shou is stupid, and Wang Zhenwen s corpse is a vegetarian meal Do you know how to govern the world, do you know how to handle government affairs Your Majesty Yang is right, we will be admonishing you to death How can you be so nonsense, admonition to death The ministers said loudly.
PS This chapter is shorter, continue to code the next chapter.You used to be a Valkyrie, and all the protoss followed you voluntarily.
Seeing this situation, Meng Jingzhe wisely did not continue to ask.Children who have been to restaurants and teahouses, watched shadow puppet shows, and listened to stories told by Lang Youfang all know Xu Yinluo.
Axi felt a little sad when he heard the words, and said, Although you are much younger than me, I always feel that you are like my relatives.With such a temptation in front of them, everyone who had originally planned to give up suddenly became eager to try again.
Meng Jingzhe held a strange shaped object in his hand, and said excitedly to Qishan Immortal Venerable.He wants to find out the whereabouts of the masked man.
Now that the time is up, the maids will naturally come back to serve His Majesty.Thinking of this, he will inevitably feel that Pai Yao is a bit lonely.
The palm print eunuch glanced at them, hesitated a little, and said Let s ask a little too much, can the adults have a way to break the situation What he really meant was, can Da Feng still be saved The reason why he didn t ask Huaiqing, but asked a few academicians, was because he didn t dare to touch the Empress, and secondly, there might not be an answer.
Although Meng Jingzhe didn t know what he was going to face next, but seeing the seriousness of these beasts, he was also worried about what happened next.He abruptly let go of the force that pushed the mountain and broke Keto Flo Gummies Shark Tank Episode: Are They Worth It? Af Betafood Keto Diet the city.
If the enemy is Xu Qi an, it shouldn t be so quiet.head.No fruit bit Liuli Bodhisattva raised his willow eyebrows, and his voice revealed a rare coldness You killed the love saving Arhat, and the prison officer promised that he will only be imprisoned for three years, and his life will not be taken.
Yes, I can be promoted to half step Martial God, but getting close to the desert is tantamount to a dead end.The sky spiders lying on the ground at the side are all standing behind Ah Jing, It was as if a team had already started.
In order to avoid the scene just now, he took back the shark bead, cupped his hands and said I have been out at sea for several months, so I will go back to my residence first.
He was warning the leaders of the Gu tribe who wanted to help.I can t elaborate on the details.I can t judge whether it is good or bad at present, but rest assured, it is not a direct and terrible disaster.
In Meng Jingzhe s eyes, dead bodies were just dead bodies.But at this time, a purple lightning bolt suddenly fell from the sky, striking towards Meng Jingzhe s soul.
The woman s voice rang in Meng Jingzhe s ears.Meng Jingzhe saw a girl who was blind in both eyes, and she rushed towards the evil god without hesitation.Even if Xu Ningyan came, he might not see the supervisor.
Long Yinjian felt that he was wronged, so he couldn t help defending himself.Yunxi s subordinates happened to meet her face to face, and with just one glance, they saw the shiny equipment on Ye Shenglan s soldiers, and immediately salivated enviously.
I ve made it so clear, but you still don t understand Meng Jingzhe asked.He was slowly lifted up, and at the bottom of the flowing shadows was Xu Qi an holding up the mountain.
A Xi is not such a fragile person, she just needs a Best Keto Diet Online Building a Brand: The Story Behind Shark Tank’s Keto Brand listener, and Meng Jingzhe, who can t speak at this time, Be the best listener.I have been reluctant to marry for a long time.I secretly pay attention to the government and cultivate cronies.
Yes, I can be promoted to half step Martial God, but getting close to the desert is tantamount to a dead end.Go to that half.The masked man was silent.Qishan Immortal Venerable said again I Can The Keto Diet Cause Hair Loss Lainey Wilson Weight Loss: How the Country Singer Achieves Her Fitness Goals have paid so much for you, betrayed the sect, poisoned senior brother, can t you give me such a small thing Meng Jingzhe, who was eavesdropping, was startled when he heard this.
The big eyeballs on Xu Qi an s wrist lit up, and he appeared on the altar, between the statues of Confucian saints and witch gods.It s just that he didn t expect that he would meet a stubborn person.
Meng Jingzhe heard the words , Wen Sheng said If you can t think of it, don t think about it.Seeing the future involves extremely high and profound rules, unless it completely replaces the way of heaven and becomes the will of Kyushu, can it truly control the secrets of heaven.
Among those things, except for some things, the rest are children s toys.Here s a name calling to complain about the eagle, 30,000 words are updated a day, what the hell is this a human thing Personal friendship is good, but I still want to kill him dog head.
