Optical and Scintillation Properties of Ce-doped 20CsCl-20SrCl2-60ZnCl2 Glasses

Ce-doped 20CsCl-20SrCl2-60ZnCl2 glasses were investigated for their optical and scintillation properties. Under X-ray irradiation, a broad emission peak at approximately 350 nm with a shoulder peak at 375 nm was observed, and its origin was attributed to Ce3+. In the pulse height spectrum under 241Am alpha-ray, the glass doped with 0.05% Ce exhibited the highest light yield (LY) of 25 ph/MeV (138 ph/5.5MeV-alpha) among zinc-halide-based glasses. The afterglow levels of the samples were superior to that of commercial CsI:Tl.
