Abstract:
In this paper, the network structure of Er3+ doped tellurite glass with conventional composition TeO2-ZnO-Na2O was modified by adding GeO2 oxide, and the impact of this modification on the near-infrared luminescence property of Er3+ was investigated. The enhancement of 1.53 μm band by about 26.7% in Er3+-doped tellurite glass after the addition of GeO2 oxide is attributed to the improved local environment around Er3+ ions. The XRD pattern, Raman spectrum and Judd-Ofelt intensity parameter disclosed the changes in network structure. The DSC curve showed an improvement in thermal stability. The fluorescence decay curve demonstrated an increase in lifetime. All of these indicated the positive effect of GeO2 addition, which is of great significance for determining the suitable glass matrix to further improve the luminescence properties of doped ions.
