Researchers have developed technology to produce next-generation composite glass for lighting LEDs and smartphone, television, and computer screens. The technology was a step forward in perovskite nanocrystal technology since previously, researchers were only able to produce this technology in the bone-dry atmosphere of a laboratory setting.
The emitting materials are made from nanocrystals, also called lead-halide perovskites. They can harvest sunlight and concert it into renewable electricity, playing a vital role in low-cost and high-efficiency solar cells and applications like lighting. The nanocrystals, however, are extremely sensitive to light, heat, air, and water — even water vapor in the air would kill the current devices in a matter of minutes.
The team developed a process to wrap or bind the nanocrystals in porous glass. The process is key to stabilizing the materials, enhancing their efficiency, and inhibiting the toxic lead ions from leaching out from the materials.
At present, quantum dot light-emitting diode screens are considered the best choice for image display and performance; however, the new nanocrystal technology will also offer exceptional picture quality and strength. Not only can the nanocrystals be made more robust but their op-to-electronic properties can also be tuned with greater light emission efficiency and highly desirable white light LEDs.
