The effect of rare earth on spectroscopic properties of gamma irradiated tellurite and borate glasses

Several optical applications demands for enhanced optical response of irradiated glasses. The introduction of rare earth (RE) ions into different matrices is considered as vital aspect in the advancement of optical devices. An extensive spectroscopic studies on irradiated RE-doped (Er³⁺, Dy³⁺) glasses samples had been done. The aim of study was to highlight the role of RE ions on the gamma irradiated glasses having different glass formers (borates, tellurites). Our studies revealed that the glasses with rare earth doping showed less changes in their characteristic properties after gamma irradiation, which indicates that these glasses are more resistant to gamma radiation as compared to the base glass
