Abstract

Er$3+) doped tellurite glasses with various Na₂O/Li₂O, Na₂O/K₂O and K₂O/Li₂O ratios were prepared. Absorption and emission spectra, glass transition temperatures, crystallization temperatures, densities, and refractive index of these glass samples were characterized. For all studied glass samples, the highest effective linewidth was obtained with mixed alkali molar ratio of Na₂O/Li₂O equals 1, Na₂O/K₂O equals 1 and K₂O/Li₂O equals 1. The studied glasses have a (T_x- T_g) exceeding 100 degree(s)C, indicating these glass samples are stable against devitrification. In addition, Judd-Ofelt analysis of several glasses was also performed.
