Abstract: In order to obtain the tellurite glass with good thermal stability and high-intensity luminescence, WO3 is doped into the TeO2-ZnO-Na2O system to improve the anti-devitrification and thermal stability of the glass. The results show that the ΔT of the tellurite glass increases from 110 °C without WO3 to 142 °C with WO3 content of 20 mol%. On the basis of thermal stability study of tellurite glass, the spectral properties of single-doped Er3+ and Er3+/Yb3+ co-doped tellurium tungstate glasses are further studied. The research results show that under the co-doping conditions of Er3+/Yb3+ , the energy transfer between Er3+/Yb3+ improves the absorption efficiency of Er3+ ions for 980 nm pump light, and the luminescence intensity in the 1.5 μm band is enhanced. Finally, Er3+/Yb3+ co-doped tellurium- tungstic glass with high-intensity 1.5 μm band emission is obtained, indicating that the co-doping of Er3+/Yb3+ is an effective method to achieve high-intensity luminescence in the 1.5 μm band.
