测量了不同温度和不同Pr 3+浓度下Pr 3+在几种重金属氟化物玻璃中的光学性质。用Judd-Ofelt理论和Kornienko等人提出的修正方法分析了由吸收和光致发光测量得到的振子强度f，发现计算值与实验值符合较好，并测量了脉冲激发后3 P0和1D 2能级的光致发光衰减
The optical properties of Pr 3+ in several heavy metal fluoride glasses have been measured at different temperatures and for different Pr 3+ concentrations. Oscillatorstrengths (f) derived from absorption and photoluminescence measurements have been analysed using the Judd-Ofelt theory as well as some modifications proposed by Kornienko et al. A reasonable agreement among calculated and experimental «f» values has been found. The decays of the photoluminescence emissions from the 3 P 0 and 1 D 2 levels after pulsed excitation have also been measured
