Abstract

Scintillators have become essential materials in modern society since they find applications in diverse fields such as security screening, resource exploration, and medical imaging.NaI is widely used as a host material for scintillators, but its strong hygroscopicity limits long-term use.In this study, we evaluated the scintillation properties of NaBr, which exhibits lower hygroscopicity than NaI.In scintillation spectra, NaBr transparent ceramics exhibit some emission peaks due to self-trapped excitons and some lattice defects.The light yield of NaBr transparent ceramics is estimated to be 1,000 photons/MeV.
