Rare Earth Activated Oxyfluoride Glasses and Glass-Ceramics for Scintillation Applications
IEEE Transactions on Nuclear Science
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.
