Time-resolved emission, excitation as well as emission decay curves of CaF₂, SrF₂, BaF₂ doped with HoF₃ were investigated. Most intensive emission bands near 168 nm, having long decay time, belong to spin-forbidden transitions from 5d¹4f⁹ high spin (HS) states to ground ⁵I₈ states of Ho³⁺ ions. Weak spin allowed 5d¹4f⁹(LS)-4f¹⁰ emission band at 158 nm was observed only in CaF₂-Ho crystals. Spin allowed and spin-forbidden excitation bands were observed in all crystals near 166 and 155 nm respectively. Fast component of spin-forbidden emissions due to multiphonon relaxation to low-lying 4f¹⁰ Ho³⁺ level was observed for all crystals.
