摘要：

Cs-133 NMR was employed to study the structural characteristics and properties of perovskites at the atomic level. CsBixPb1-xBr3 perovskites doped with Bi at concentrations of 0.0059, 0.0072, and 0.0120 were studied. The importance of high-quality materials for applications in optics and photonics was noted. Cs-133 NMR showed high sensitivity for studying these concentrations of Bi, which affect the stability of perovskites and their dynamic parameters.
