Oxyfluoride glasses 49SiO2-6Al2O3-24Li2O-20LaF3 activated with Tb, Ce, Eu have been synthesized and studied. After heating at 580C and 750C crystalline phases were obtained. The samples were studied by DTA (Differential thermal analyzer), CL (cathodoluminescence), XRD (X—ray diffraction), SEM (scanning electron microscope), EDS (energy dispersive x-ray spectroscopy) methods. We found out that presence of crystalline phase enhances the CL of Tb activated samples significantly; whereas, the shortest decay time of 0.29 mks has been observed for less intense Ce doped glass sample.
