Application of original and modified Judd-Ofelt theories to the 1S 0 state of Pr 3+-doped SrAl 12O 19 and LaF 3
Abstract
The main fluorescence branching ratios of 1S 0 state in SrAl 12O 19:Pr 3+and LaF 3:Pr 3+ have been determined by vacuum ultraviolet excitation. The original and modified Judd-Ofelt analyses both with normalized method were applied to the absorption spectra of Pr 3+ to get three phenomenological intensity parameters: Ω2, Ω4, and Ω6. They were subsequently employed to calculate the branching ratios and decay times of the Pr 3+1S 0 level in SrAl 12O 19 and LaF 3. The result showed that in both hosts, the modified Judd-Ofelt theory with normalized method provided a better agreement with experimental data than the original one.
