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.
