The results of the synthesis and study of the spectral and structural properties of borate glasses with (Cs,Rb)PbBr3 perovskite nanocrystals are presented. (Cs,Rb)PbBr3 nanocrystals exhibit intense narrow-band luminescence in the 510–520 nm region. With an increase in the rubidium content, the luminescence maximum of the crystals shifts to the short-wavelength region, while the luminescence quantum yield first increases to 91% and then decreases to 52%. In the rubidium absence, several perovskite-like phases of lead-cesium bromides are nucleated in the glass matrix: CsPb2Br5, Cs4PbBr6, and CsPbBr3, while with the increase of the rubidium the CsPbBr3 phase predominates. The glass matrix protects the (Cs,Rb)PbBr3 nanocrystals from the ambient atmosphere, which leads to the stability of their luminescence intensity.
