Abstract: The results of a study of time-resolved photoluminescence (PL) and energy transfer in both pure and doped with Ce3+ ions SrAlF5 (SAF) single crystals are presented. The time-resolved and steady-state PL spectra in the energy range of 1.5-6.0 eV, the PL excitation spectra and the reflectivity in the energy range of 3.7-21 eV, as well as the PL decay kinetics were measured at 8.8 and 295 K. The lattice defects were revealed in the low temperature PL spectra (emission bands at 2.9 and 4.5 eV) in the undoped SAF crystals. The luminescence spectra of the doped Ce3+:SAF crystals demonstrate a new selective emission bands in the range of 3.7-4.5 eV with the exponential decay kinetics (τ ≈ 60 ns at X-ray excitation). These bands correspond to the d-f transitions in Ce3+ ions, which occupy nonequivalent sites in the crystal lattice. © 2010 Pleiades Publishing, Ltd.
