Abstract

Spectroscopic data is presented for Pr3+-doped calcium fluorapatite (Ca5(PO4)3F) and strontium fluorapatite (Sr5(PO4)3F) crystals which were studied using polarized absorption and laser-induced fluorescence as optical probes. Complete tabulation of experimental energy levels is provided for strontium fluorapatite, where only one Pr3+ site, having C5 symmetry, is measurable. In calcium fluorapatite, at least three Pr3+ sites of appreciable concentration are evident, though the majority site is demonstrated to show similarity to the site in the strontium fluorapatite host. An unusually high crystal field splitting of Pr3+ energy levels is exhibited in both hosts. Intersite energy transfer, upconversion and cross relaxation are discussed for Pr3+ in the calcium fluorapatite crystal.
