摘要

CsPbBr

钙钛矿量子点(PQDs)在光、热、空气中会发生不同程度的降解，导致严重的荧光猝灭，限制了其在光电器件中的应用。本文采用传统的熔融淬火和热处理方法，将CsPbBr

PQDs与锌硼硅酸盐玻璃复合，成功制备了CsPbBr

PQDs@glass复合发光材料。研究表明，CsPbBr

PQDs@glass的发射峰峰值为520 nm，半峰宽(FWHM)为20 nm，是一种绿光发射材料。同时该材料具有良好的光和水稳定性，蓝光下连续照射30 d，发光强度仅降低了约4%，水中浸泡30 d，其发光强度仍能保持初始强度的95%。此外，利用CsPbBr

PQDs@glass成功封装了白光LED器件，说明该材料在照明和显示领域具有潜在的应用前景。

Abstract

CsPbBr

perovskite quantum dots(PQDs)will degrade in different degrees in light

heat and air

which limits their application in optoelectronic devices. In this paper

the CsPbBr

PQDs@glass was successfully prepared by traditional melting quenching and heat treatment methods

in which CsPbBr

PQDs and zinc borosilicate glass were composited. The results show that the CsPbBr

PQDs@glass is a kind of green emission material peaked at 520 nm with a half peak width (FWHM) of 20 nm. At the same time

the material has good light and water stability. After continuous irradiation under blue light for 30 d

the emission intensity is only reduced by about 4%. After soaking in water for 30 d

the emission intensity can still maintain 95% of its initial intensity. In addition

the white LED device is successfully encapsulated by the composite

which shows that the material has potential application in the field of lighting and display.
