Abstract

Eu3+ doped glasses and partially crystalized materials of 50ZnO:(50-x)B2O3:xWO3, x = 0, 10, 15, 20 mol% were synthesized by melt quenching. X-ray amorphous samples were prepared from the base binary composition 50ZnO:50B2O3 and from ternary composition containing 10 mol% WO3. By visual observation, phase separation in the binary zinc borate glass was established, while glass with 10 mol% WO3 was found to be homogeneous. Partially crystalized specimens comprising ZnWO4 as crystalline phase were obtained from the compositions having, 15 and 20 mol% WO3. The PL emission spectra at room temperature of the prepared materials were measured.
