Abstract

Sm3+-doped gadolinium calcium phosphate glasses of the composition (70-x)P2O5: 10CaO: 20Gd2O3: xSm2O3 (PCGSm), where x = 0.05, 0.10, 0.50, 1.00, 1.50, 2.00, 2.50 and 3.00 mol% have been prepared by melt-quenching technique and investigated their photoluminescence properties. The emission spectra of Eu3+-doped glasses recorded in wavelength range 500-750 nm with 402 nm excitation. All the spectra exhibited 4 emission bands corresponding to the 4G5/2→6H5/2, 4G5/2→6H7/2, 4G5/2→6H9/2 and 4G5/2→6H11/2 transition, respectively. The peak intensities increase with the increase of concentration from 0.05 to 0.5 mol% and beyond that the quenching in the emission peak intensities have been observed. © 2016 Trans Tech Publications, Switzerland.
