    Erbium-doped tellurite-based glasses (Er3+:TeO2-ZnO-La2O3) 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 4I13/2 4I15/2 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 4I13/2 4I15/2 emission line of Er3+ ions. The optimum doping content of Er2O3 for 1.53 μm fluorescence emission is about 1.5 mol%.
