Predictions of the Spectra of the Rare-Earth Ions Ce(3+) Through Yb(3+) in theTwo Sites of Ca5(PO4)3F

摘要

The results of fitting the experimental data on Er(3+) in the two Ca2+ sites ofCa5(PO4)3F are used to predict the crystal-field parameters for the entire rare-earth series. These crystal-field parameters are then used along with the free-ion wavefunctions determined with aqueous parameters to determine a set of energy levels of the rare-earth ions Ce(3+) through Yb(3+) for both Ca(2+) sites (Cal with C(sub 3) symmetry and Ca2 with C(sub s) symmetry) in Ca5(PO4)3F. Also, the Judd-Ofelt parameters, Omega k are determined for each ion in the Cal and Ca2 sites, as well as the Zeeman g factors for the ground states. jg.
