AbstractThe regression analysis of the rise kinetics of up-conversion luminescence of the LiY_0.8Yb_0.2F_4:Tm^3+ (0.2 at %) crystal is performed. The kinetics curve is obtained with rectangular pulsed excitation by radiation from a laser diode (IR LD) with a wavelength of λ_ p = 933 nm. The most important—in these experimental conditions—mechanisms of the energy transfer from Yb^3+ ions to Tm^3+ ions are established, which are responsible for the transitions between the ground ^3 H _6 and excited ^3 F _4, ^3 H _4, ^1 G _4, ^1 D _2, and ^1 I _6 terms of the Tm^3+ ions. The durations of the relevant energy transfer processes are determined. It is shown that the energy transfer between rare earth ions in the LiY_0.8Yb_0.2F_4:Tm^3+ (0.2 at %) crystal occurs through the dipole–dipole interactions.

By activation of the host lattices Sr3La2W2O12 and Ca2La0,5Na0,5WO6 with the trivalent rare earth ions Ln3+ = Pr, Sm, Eu, Tb, Dy, Ho, Er a cathodoluminescence in the visible region is obtained. The influence of the electronic structure and concentration of the activator on the relative emission efficiency as well as the host lattice participation in the energy transfer processes are discussed.
