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.

This operation alone is enough to upgrade Wanjianfeng from a third grade magic weapon to a fourth grade magic weapon.In addition to Zuo Ancestor and him, there was also a disciple of Zuo Ancestor and his senior sister Ye Jingxian on the huge flying boat magic weapon.
It had nothing to do with a truly professional competition.When the spiritual power of the golden elixir in his body was filled, he gained enough insights into the Sword Intention Chongxiao Jue to allow him to directly break through from the peak of the late golden elixir to the realm of the Great Elder.
Every light touch of the Broken Jade Sword landed on the ridge of the super grade sword shaped magic weapon.He didn t know how the powder was made, and it was almost integrated with the spiritual soil.
Although he has seen many sword intentions, no matter which kind of sword intention can achieve the effect of breaking through spells, there is still a gap between the one sword that can break through all spells as he imagined.The spiritual power of hundreds of golden elixir monks in the war flying boat were gathered together.
He no longer stayed, recalled the golden corpse and black shield, turned around and left here.

Don t worry, Mr. Luo, Zhao has already made arrangements.The battle for Huangquan Cave failed. Although we lost the right to use Huangquan Cave for two years, it was nothing.
At this time, Luo Chen was even more curious about the small tree.The inner city wall was five or six meters high, forming an arc and surrounding a large area inside.
Luo Chen, who had already perfected his sword power, once again used the Mountain Pressure , but it made the entire space above seem to collapse, and the force of oppression rolled down
A series of annihilation sounds sounded. When encountering this oppressive force, more than a dozen sword shadows were instantly annihilated.
It was as if I was momentarily evacuated. In the end, in order to prevent Jian Wutian from seeing that he was at the end of his strength, Luo Chen used the remaining qi in his veins The Benefits of Number 8 Sleep Gummies for a Restful Night's Sleep (bdLgl)
