白光LED用量子点玻璃的制备方法及应用研究进展

白光LED用量子点玻璃不但具有量子点高荧光效率、发光波长可调和较窄的发射波长等新颖的光学特性,而且量子点的热稳定性差和水氧抵抗性差的问题也很好的得到了解决,可以有效的避免封装材料黄化老化、发光不均匀和出现光斑等传统封装白光LED出现的问题。综述了白光LED用量子点玻璃的制备方法及其在LED的应用,并对白光LED用量子点玻璃的荧光效率和无铅、无镉量子点玻璃的研制提出了进一步展望。

Research Progress in Preparation and Application of Quantum Dot Glass for White LED

Quantum dot glass for white LEDs not only displays novel optical characteristics such as high fluorescence efficiency, adjustable luminous wavelength, and narrow emission wavelength, but also solves the problems of poor thermal stability and poor resistance to water and oxygen of quantum dots. Thus, the problems of traditional packaging white LEDs such as yellowing and aging of packaging materials, uneven light emission, and light spots can be effectively avoided. The preparation method of quantum dot glass for white LED and its application in LED were reviewed, and further prospects for the fluorescence efficiency of quantum dot glass for white LED and the development of lead-free and cadmium-free quantum dot glass were put forward.
