LUMINESCENT GLASS WITH PEROVSKITE NANOCRYSTALS CsPbBr AND CsPbI Russian patent published in 2024 - IPC G02B1/02 C03C4/12 

FIELD: optical material science.

SUBSTANCE: invention relates to optical material science and can be used in making lasers, polarizers, diodes, solar cells, photodetectors and luminescent optical materials. Essence of the proposed technical solution lies in the fact that luminescent glass with perovskite nanocrystals CsPbBr₃ and CsPbI₃ refers to a sodium-zinc-borogermanate system in which nanocrystals of CsPbBr₃ and CsPbI₃ are formed at the following ratio of components, mol.%: GeO₂ 36.46-42.39; B₂O₃ 22.59-26.26; Na₂O 4.77-6.73; Cs₂O 5.18-5.90; Br 0-8.01; ZnO 4.81-5.59; K₂O 2.63-6.2; I 0-7.68; TiO₂ 1.79-3.15; PbO 2.17-2.53; P₂O₅ 1.32-1.53.

EFFECT: high mechanical strength, chemical resistance and transparency of the material with perovskite nanocrystals CsPbBr₃ and CsPbI₃.
