| 摘 要： | 测量了不同掺杂浓度下Ｙｂ３＋离子在氟化物及磷酸盐玻璃中的吸收光谱、发射光谱和Ｙｂ３＋离子的荧光寿命，计算了Ｙｂ３＋离子的发射截面σｅ，分析了Ｙｂ３＋离子掺杂浓度对其发光强度和荧光寿命的影响。实验结果表明，Ｙｂ３＋离子掺杂浓度较低时，对其荧光强度和荧光寿命没有显著影响。在高掺杂浓度时，发生了浓度猝灭效应，使Ｙｂ３＋离子荧光强度降低，荧光寿命下降。对浓度猝灭效应产生的机理进行了分析和解释。

| Abstract: | Absorption spectra, emission spectra and fluorescence lifetime were measured with different concentrations of Yb3+-doped, the emission cross section σe of Yb3+ was calculated. Dependence of luminescence intensity and fluorescence lifetime on concentration of Yb3+ was analyzed. No remarkable influence of concentration of Yb3+ ions on luminescence intensity and fluorescence lifetime was observed in the case of low level Yb3+ doped. Concentration quenching occurred when high level Yb3+ was doped. Luminescence intensity and fluorescence decreased because of it. The mechanism of concentration quenching was discussed and explained. |
