Název v původním jazyce

Determination of the position of the 5d excited levels of Ce3+ ions with respect to the conduction band in the epitaxial films of the multicomponent (Lu,Gd)3(Ga,Al)5O12:Ce garnets

Popis výsledku v původním jazyce

Temperature dependences of the intensity and decay kinetics of the Ce3+ - related photoluminescence and characteristics of thermally stimulated luminescence are investigated for the epitaxial films of the multicomponent garnets of the type of Lu3xGdxGayAl5-yO12:Ce. Different methods are used for the determination of energy distances between the excited 5d1 and 5d2 levels of Ce3+ ions and the conduction band (CB). The 5d1-CB energy distance is found to decrease with the increasing Ga3+ content. The most drastic decrease which was observed, is suggested to arise from the change in the Ga3+ position from the smaller tetrahedral to larger octahedral Al3+ sites. This effect is explained by the lattice distortion due to the substitution of smaller Lu3+ and Al3+ ions by larger Gd3+ and Ga3+ ions.n
