Abstract
Homogenous and transparent 50ZnO:40B2O3:10WO3:xEu3+, x = 0, 0.1, 0.5, 1, 2, 5 and 10 mol% glasses were obtained by melt quenching method. Their crystallization behavior was studied by Differential Thermal Analysis (DTA) and X-ray Diffraction Analysis (XRD) measurements. It was established the formation of ZnWO4 as a single crystalline phase after thermal treatment of the glasses containing from 0 to 2 mol% Eu2O3. Several crystalline phases: ZnWO4, ZnB4O7 and H3BO3 were detected in the XRD patterns of glass crystalline samples containing 5 and 10 mol% Eu2O3. The PL emission spectra at room temperature of the prepared materials were measured.
