[20p-PB5-49] Preparation of CaF2:Sm transparent ceramics and RPL properties
Keywords:radio-photoluminescence, samarium, calcium fluoride
In this study, we have prepared Sm-doped CaF2 transparent ceramics and characterized the radio-photoluminescence properties. The sample preparation was performed by the spark plasma sintering technique, and we have successfully prepared ceramic samples in a transparent form. The as-prepared samples showed only Sm3+ active while X-ray irradiation activated Sm2+ in photoluminescence, which was observed as a PL peak around 730 nm.
