摘要：

Absorption and UV fluorescence spectra of Pr3+ weakly doped alkaline earth fluoride single crystals have been recorded and interpreted in terms of f-->d transitions. Short fluorescence lifetimes have been measured. The emission spectra and the decay profiles of Pr-doped BaF2 have been studied as a function of photon excitation energy. This latter system exhibits cross-luminescence and excitonic fluorescence in addition to d-f luminescence of Pr3+.
