Abstract
We report the changes of the 5D J - 7F 0( J = 2, 1, 0) transition probability with composition y and its effect on the hole burning quantum efficiency in the Sr y Ba 1− y FCl 0.5Br 0.5:Sm 2+ system. We observed that the 5D J - 7F 0 transition probability increases with the increase of Sr concentration. This result is attributed to the reduction of the energy separation between the 5D J level and the 4f5d bands, which makes the electron wave functions of 5D J states mix further with that of the 4f5d states. The dependence of the hole-burning quantum efficiency on the 5D J - 7F 0 transition probability was derived by the dynamical equations of the spectral hole burning of divalent samarium. Furthermore, the hole-burning experiments in SrFCl 0.5Br 0.5:Sm 2+ and BaFCl 0.5:Sm 2+ were performed under the same conditions. The experimental results present that the hole-burning quantum efficiency of SrFCl 0.5Br 0.5:Sm 2+ is higher than that of BaFCl 0.5Br 0.5:Sm 2+.
