Energy Levels and Line Intensities for the Ground Configuration of Pr3+ in Liyf4.

Abstract

In the present work, a systematic spectroscopic investigation of trivalent praseodymium (Pr3+) in lithium yttrium fluoride (LiYF4 or YLF) was undertaken. High-resolution polarized absorption and fluorescence spectra were measured at temperatures between 10 and 300 K and analyzed to determine the energy levels of the 4f2 ground configuration. Spectroscopic data previously reported for Pr3+: YLF either have been incomplete or have led to incorrect energy assignments. Experimental line intensities for Pr3+ in YLF also were determined and are reported for the first time. The spectra were analyzed in detail to obtain empirical parameters that describe the effects of the host lattice on the Pr3+ energy levels.
