摘要
根据Judd—Ofelt理论计算了Er^(3+):ZBLAN玻璃中Er^(3+)的实验与理论谱线强度;用最小一乘法拟合实验与理论谱线强度得到三个强度参数C_λ(λ=2、4、6)。然后计算了各激发态自发辐射电偶极跃迁几率及有关能级的磁偶极跃迁几率、辐射寿命和荧光分支比。
Optical-absorption spectra and levels are presented for Er^(3+) in ZBLAN glass.Measured spectra-line strengths of the transition between J manifolds at room tem--perature are compared with the calculated electric and magnetic dipole spectra-linestrengths. The predicted spontaneous-emission probabilities and radiative lifetimeare given.
