Studies of radiation defects in cerium, europium and terbium activated oxyfluoride glasses and glass ceramics

摘要

Terbium, cerium and europium activated oxyfluoride glasses and glass ceramics have been studied by thermally stimulated luminescence (TSL) and optical absorption techniques after the X-ray irradiation. A creation of colour centres in oxyfluoride glass matrix and TSL peaks depending on the activator type were observed. LaF3 and rare earth activators were analysed by SEM-EDS. (C) 2014 Elsevier B.V.
