Metal halide perovskites CsPbHal₃ (Hal = Br, I) are a widely studied class of materials for applications in photonics and optoelectronics. The low chemical stability of perovskite nanocrystals limits their practical applications. One approach to improving stability is to form nanocrystals within an inorganic glass matrix, which simultaneously preserves their luminescent properties and protects them from environmental influences. This study proposes to investigate the influence of the PbO/KHal (Hal = Br, I) ratio and the total concentration of precursors in the glass on the formation of perovskite nanocrystals and their optical properties. The results obtained provide new insights into the processes of perovskite formation and photoluminescence properties in inorganic glasses.
