摘　　要：Erbium-doped tellurite-based glasses （Er3＋：TeO2-ZnO-La203） are prepared by the conventional melt-quenching technique, and concentration-dependent luminescence properties of Er3＋ are investigated. A significant spectral broadening of the 1.53 μm fluorescence corresponding to 4113/2 4115/2 transition is observed, and the fluorescence decaying becomes a nearly exponential way with the increasing Er3＊concentration. Radiation trapping is evoked to explain the broadening of 4113/2 4115/2 emission line of Er3＋ ions. The optimum doping content of Er203 for 1.53 μm fluorescence emission is about 1.5 mol%.
