摘要：

The polarized fluorescence of a total of 12 Ho3+ ion centers present in CaF2- and SrF2-type CrystalS and having a variety of Ho3+ ion symmetries has been analyzed to give possible model assignments. In contrast to the earlier results for SrF2:Er3+, which has a dominant trigonal symmetry center, the principal center in SrF2:Ho3+ is determined to have tetragonal symmetry. Crystal-field analyses are reported for both the tetragonal and trigonal symmetry centers, together with fluorescence-lifetime data for these centers.
