CsPbBr₃:xBi³⁺ quantum dot glass was prepared by using traditional melting-quenching and heat treatment processes. The effects of Bi doing on the sinter of the precursor of glass and the crystalline of the perovskite quantum dot were discussed detailly. By doping Bi₂O₃ into the borosilicate glass matrix, the melting temperature was reduced to 900 C. The tunable emission of CsPbBr₃ quantum dots from 523 to 493 nm was achieved with suitable Bi₂O₃ doping. Due to the protection of the inorganic glass matrix, the prepared CsPbBr₃ quantum dots still exhibit excellent thermal stability after multiple thermal cycles and thermal shocks. This provides a good solution to the problem of poor thermal stability of perovskite quantum dots.

CsPbBr ₃：xBi ³⁺量子点玻璃是通过传统的熔融淬火和热处理工艺制备的。详细讨论了Bi的添加对玻璃前驱体的烧结和钙钛矿量子点晶体的影响。通过将Bi ₂ O ₃掺杂到硼硅酸盐玻璃基体中，熔融温度降低到900℃。通过适当的Bi ₂ O ₃掺杂，可实现523至493 nm的CsPbBr ₃量子点可调发射。由于保护了无机玻璃基质，所制备的CsPbBr ₃在多次热循环和热冲击后，量子点仍具有出色的热稳定性。这为钙钛矿量子点的热稳定性差的问题提供了很好的解决方案。
