摘　　要：实验研究了氟磷玻璃中［ＰＯ３］－含量的变化对Ｙｂ３＋的光谱性质的影响。结果表明．随着［ＰＯ３］－含量的增大，Ｙｂ３＋的受激发射截面积增大，吸收光谱和荧光光谱谱线位置向长波方向移动，反映出Ｎｅｐｈｅｌａｕｘｅｔｉｃ效应。随［ＰＯ３］－含量增大，玻璃中引入的ＯＨ－离子浓度增大，极大降低了Ｙｂ３＋荧光寿命。The spectral Properties of Yb3+ are investigated in fluorophosphate gi￣ withdifferent [PO3]- contentS. In fluorophosphate glasses the results indicate that as the [PO;]content increases in glasses; the stimulated emission cross section of Yb3+ increases; and theabsorption and emission Peaks shift to longer wavelengths;showing the Nephelauxeticeffect.Also; with the increase of [PO3]- content in the glass;more OH- exists in theglass;exertS strong influence on the fluorescence lifetime of Yb3+.
