Application of a modified Judd-Ofelt theory to praseodymium doped fluoride glasses

Application of a modified Judd-Ofelt theory to praseodymium doped fluoride glasses
Application of a modified Judd-Ofelt theory to praseodymium doped fluoride glasses
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 1D2 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 1D2 transition.

Abstract

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 1D2 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 1D2 transition.
