Abstract

The effect of copper ion doping on the γ-ray irradiation resistance of Mn2+and Pr3+doped phosphate glasses has been studied. UV-visible transmission spectra and photoluminescence spectra have been measured before and after γ-irradiation to characterize the radiation-induced defects. The electron paramagnetic resonance spectra of the irradiated samples with, and without Cu ions have been compared to show the ability of Cu ions to suppress the generation of radiation-induced color centers. The differential transmission spectra and the radiation-induced absorption coefficients have also been calculated for discussion of the observed phenomena. The much improved γ-irradiation resistance of Mn2+and Pr3+doped phosphate glasses has been demonstrated through CuO co-doping. © 2013 Elsevier B.V. All rights reserved.
