摘要：

The anti-Stokes luminescence spectra of Ho : CaF2 crystals corresponding to the (5)G(4) -> I-5(8), (5)G(5) -> I-5(8), F-5(3) -> I-5(8), F-5(4)(S-5(2)) -> I-5(8), F-5(5) -> I-5(8), S-5(2) -> I-5(7), I-5(4) -> I-5(8), I-5(5) -> I-5(8), F-5(5) -> I-5(7), F-5(3) -> I-5(6), I-5(6) -> I-5(8), F-5(5) -> I-5(6), and I-5(5) -> I-5(7) transitions upon excitation of the I-5(7) level of Ho3+ ions are studied. A method for visualisation of IR radiation in the two-micron range using Ho:CaF2 crystals is proposed. The energy efficiency of conversion of two-micron laser radiation to radiation in the red spectral range 620-690 nm by a 1 mol % HoF3:CaF2 crystal is estimated to be no higher than 0.02 %.
