Effect of Mg2+ co-doping on the photo- and thermally stimulated luminescence of the (Lu,Gd)3(Ga,Al)5O12:Ce epitaxial films
Original language description
Photoluminescence and thermally stimulated luminescence of Ce3+-doped (Lu,Gd)3(Ga,Al)5O12 epitaxial films co-doped with different content of Mg2+ ions are investigated in the 60–500 K temperature range under excitation in the Ce3+-related 4f→5d absorption bands and in the absorption bands arising from the 8S7/2→6IJ and 8S7/2→6PJ electronic transitions of Gd3+ ions. Influence of Mg2+ ions on the Ce3+-related luminescence intensity, spectrum, decay kinetics, temperature dependence of the emission intensity, and the activation energy of the luminescence thermal quenching is studied. The shortening of the decay time and simultaneous reduction of its light yield are explained by the presence of {Ce3+-Mg2+} centers. Co-doping with Mg2+ results in the reduction of the afterglow and thermally stimulated luminescence and shortening of the afterglow decay kinetics. It influences also defects creation spectra and the activation energy of the photostimulated defects creation.n
