Formation of CsSnBr3 microcrystals in CsBr:Sn (1 mol.%) crystals is revealed after the long-term annealing (t = 100 h, T = 200 C). Luminescent-kinetic parameters of CsBr:Sn (1 mol.%) crystals are measured using the excitation with synchrotron radiation. The process of energy transfer from the host to the aggre-gates is discussed.

Keywords: CsSnBr3 microcrystals, luminescence; energy transfer
