摘要 对制备的不同掺杂Er3+ 浓度的硅酸盐玻璃 ,测定了吸收光谱和荧光光谱 根据玻璃的光谱特性计算了玻璃吸收面积并确定出体系的最佳掺杂Er2 O3浓度为 0 .2左右 根据Judd Ofelt理论拟合出光谱强度参数Ωλ(λ =2 ,4 ,6 ) ;结果分析表明 :随着Er3+ 离子浓度的增加 ,光谱强度参数Ω2在增大 ,Ω6 在减小 ,说明玻璃的共价性能增强 ,Er Er 3+-Doped silicate glasses were fabricated.Absorption spectra and emission spectra of the glasses were measured.The better Er 2O 3 concentration was about 0.2 The Judd-Ofelt parameters Ω λ(λ=2,4,6) of the glasses were calculated and Ω 2,Ω 6 were analyzed.
