Abstract

We present a comprehensive spectroscopic study of C $_{2v}$ point-group symmetry sites in Sm $^{3+}$ :CaF $_2$ /SrF $_2$ codoped with either NaF or LiF. Data includes electron paramagnetic resonance measurements of Zeeman and hyperfine interactions for the ground state, as well as site-selective excitation and fluorescence spectroscopy up to the $^{4}$ G $_{5/2}$ multiplet. Inclusion of the EPR data allowed us to determine unique crystal-field parameters. The parameters provide information about the geometry of the sites and the nature of the interactions between the Sm $^{3+}$ dopant and the alkaline earth co-dopant.
