文摘

Tb, Ce, Eu activated oxyfluoride glass-ceramics with the composition SiO₂?¡¤?Al₂O₃?¡¤?Li₂O?¡¤?LaF₃ have been studied by cathodoluminescence (CL). We compared CL intensities and decay times of the Tb, Ce, Eu activated glass-ceramic samples and observed that the Tb activated sample has the most intense luminescence, but the Ce activated sample has the shortest decay times. Induced optical absorption and thermostimulated luminescence have been observed after X-ray irradiation of samples.
