中文摘要	测量了不同掺杂浓度下Er^3+离子在碲酸盐玻璃中的吸收光谱、发射光谱和Er^3+离子的荧光寿命，计算了Er^3+离子的发射截面σc，分析了Er^3+离子掺杂浓度对其发光强度和荧光寿命的影响．结果表明，Er^3+离子掺杂浓度较低时，对其荧光强度和荧光寿命没有显著的影响；掺杂浓度高时，出现了浓度猝灭效应，使Er^3+离子荧光光强度降低，荧光寿命下降．实验确定了掺杂浓度最优值，同时对浓度猝灭机制进行了分析．; Absorption spectra, emission spectra and fluorescence lifetime of Er3+ ions were measured for TeO2-ZnO-Na-2 O-K2O glasses with different doping concentrations of Er3+ and the emission cross section sigma(c) of Er3+ was calculated. Dependence of luminescence intensity and fluorescence lifetime on concentration of Er3+ were analyzed. The influence of concentration of Er3+ ions on luminescence intensity and fluorescence lifetime was unconspicuous in the case of low doping level of Er3+. However, high concentration of Er3+ ions resulted in the concentration quenching, which reduced the luminescence intensity and fluorescence lifetime. The optimum concentration of Er3+ ions was determined for TeO2-ZnO-Na2O-K2O glasses, and the mechanism of concentration quenching was also discussed and explained in detail.
