Description
Absorption, emission, excitation spectra of CaF2, SrF2, BaF2 crystals doped by PrF3 in concentration ranging from 0.005% to few molar % were studied in 1.4-10 eV spectral region. Specific type of Pr centres possessing photon cascade emission (PCE active) was observed in all crystals. Concentration of centres monitored by excitation and emission spectra grows superlinearly with increasing of Pr concentration in SrF2 and BaF2 crystals. A new additional absorption band at 7.0 eV which coincided with excitation band of PCE-active centres was observed in CaF2-Pr crystals. The absorption coefficient of this band grows twice that coefficient of 5.7 eV band of single Pr centres.
