Abstract

Oxyfluoride glasses 49 SiO ₂₂O ₃. 24 Li ₂O. 20 LaF} ₃ activated with Tb, Ce, Eu have been synthesized and studied. After heating at 580° and 750° crystalline phases were obtained. The samples were studied by DTA (Differential thermal analyzer), CL (cathodoluminescence), XRD (Xray 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 μs has been observed for less intense Ce doped glass sample.
