Title: Photoluminescence properties of Tb-Eu-Mn-codoped fluoroborate glasses under γ-irradiation

We report here an energy transfer from Tb{sup 3+} to Eu{sup 3+}, Mn{sup 2+} and Eu{sup 2+} to Tb{sup 3+} and Mn{sup 2+} for an un-irradiated and γ-irradiated B{sub 2}O{sub 3}-Al{sub 2}O{sub 3}-Na{sub 2}O-SrF{sub 2} glass samples, respectively. The blue emission from Eu{sup 2+} ions as well as green and red emission from Tb{sup 3+}, Eu{sup 3+}, and Mn{sup 2+} ions will contribute to the generation of white light while excited at 339 nm using a xenon lamp. Furthermore, the chromaticity color coordinates, correlated color temperature, and quantum efficiency parameters are calculated for all the glass samples, and their relative variations with respect to γ-irradiation dose are presented.
