摘要

通过改进的一锅热注入法

研究了不同Ga

的量掺杂CsPbBr

后的荧光光谱变化

并且高荧光量子产率(Photoluminescence Quantum Yield，PLQY)在Ga

和Pb

的进料摩尔比为1∶1的时候达到最高

是47%的蓝光。本文成功地将掺杂Ga

的钙钛矿量子点负载到了硼酸钴晶体材料上

发现其荧光强度在很长一段时间都没有明显的猝灭现象

这增强了钙钛矿量子的稳定性。

Abstract

We studied the fluorescence spectrum changes after doping CsPbBr

with different amounts of Ga

by an improved one-pot hot-injection method

and photoluminescence quantum yield (PLQY) reached the highest when the molar ratio of Ga

and Pb

was 1∶1

which was 47% blue light. We successfully loaded Ga

-doped perovskite quantum dots onto the cobalt borate crystal material

and found that the fluorescence intensity has no obvious quenching phenomenon for a long time

which enhances the stability of the perovskite quantum.
