Luminescence Properties of Sn-Containing Microcrystals in CsBr:Sn Crystal

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 pa-rameters 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.
