RARE-EARTH DOPED FLUOROCHLOROZIRCONATE (FCZ) GLASSES AND GLASS-CERAMICS: SELECTED THERMAL PROPERTIES AND X-RAY LUMINESCENCE IN SAMARIUM DOPED FCZ

摘要

Recently, a new class of rare-earth (RE) doped fluorochloro-zirconate (FCZ) glass-ceramics has been developed and studied with thegoal of using these materials in indirect conversion x-ray imaging applica-tions. We report selected thermal and x-ray induced luminescence (XL)properties of rare-earth (EuF_2and SmF_3) doped fluorochlorozirconateglasses and glass-ceramics, and highlight some of their interesting proper-ties. Sm~3+-doped FCZ glasses exhibit XL even in the unannealed state,while annealing at a temperature of 250°C in a reducing atmosphere (5% H_2and 95% Ar) significantly enhances the XL efficiency.
