Abstract
Absorption and UV fluorescence spectra of Pr3+ weakly doped alkaline e arth fluoride single crystals have been recorded and interpreted in te rms of f-->d transitions. Short fluorescence lifetimes have been measu red. The emission spectra and the decay profiles of Pr-doped BaF2 have been studied as a function of photon excitation energy. This latter s ystem exhibits cross-luminescence and excitonic fluorescence in additi on to d-f luminescence of Pr3+.
