Since Tl-doped NaI was discovered, the scintillation properties of Tl-doped alkali iodides were investigated by many researchers. However, there are a few reports on the scintillation properties of Tl-doped alkali bromides. Therefore, in this study, we synthesized CsBr crystals with several concentrations of Tl and examined the Tl concentration dependence of the photoluminescence and scintillation properties.
