Abstract

Copyright (c) 1997 Elsevier Science B.V. All rights reserved.Concentration series of YLF:Tm and YLF:Tm-Ho crystals were examined. The intraionic transition probabilities and interionic energy transfer processes were studied both theoretically and experimentally. The method of quantum mechanical modelling was employed for theoretical calculations. On the basis of experimental data and theoretical estimates, the predominant mechanism of energy transfer was determined. Concentration dependence of the rate of luminescence self-quenching was calculated and compared with the data obtained from the luminescence decay curves. Tm-Ho energy transfer rate in co-doped crystals for the lowest Tm and Ho energy levels was examined. Good agreement between the experimental and calculated data was obtained in all cases.
