摘要：

Using the original Judd-Ofelt theory and a more recent modified Judd-Ofelt theory, the radiative properties of praseodymium in a series of halide glasses are predicted. Experimental and measured oscillator strengths are presented and Judd-Ofelt parameters are determined by both methods for all glasses. The calculated radiative lifetimes are compared with the experimentally measured values for the D-1(2) energy level and the suitability of the two models are compared. Results show that the modified theory provides better agreement with the experimentally measured lifetimes for the D-1(2) transition.
