Abstract

Er3+ doped tellurite glasses with various Na2O/Li2O, Na2O/K2O and K2O/Li2O ratios (0-4.5) were prepared at 850°C using a platinum crucible. The effect of relative alkali content on absorption linewidth in erbium-doped tellurite glasses was investigated. The highest effective linewidth was obtained from glass samples with mixed alkali molar ratio of Na2O/Li2O = 1, Na2O/K2O = 1 and K2O/Li2O = 1. Glass transition temperature, crystallization temperature, density, refractive index, Judd-Ofelt parameters and emission cross-section of Er3+ doped tellurite glasses are also reported.
