    Influence of gallium content on Ga3+ position and photo-and thermally stimulated luminescence in Ce3+-doped multicomponent (Y,Lu)(3)GaxAl(5)xO(12) garnets

  • Original language description

    Photoluminescence, thermally stimulated luminescence (TSL) and EPR characteristics of the Ce3+-doped single crystals of multicomponent Y1Lu2GaxAl5-xO12 and Lu3GaxAl5-xO12 garnets with different Ga contents (x = 0, 1, 2, 3, 4, 5) excited in the Ce3+-related absorption bands are investigated in the 9-500 K temperature range. The distribution of Ga3+ and Al3+ ions in the crystal lattice is determined by the NMR method. The relative number of Ga3+ ions in the tetrahedral crystal lattice sites, the maxima positions of the TSL glow curve peaks and the corresponding trap depths are found to decrease linearly with the increasing Ga content. At the same time, the reduction of the activation energy Ea of the TSL glow curve peaks creation under irradiation in the 4f-5d1 absorption band of Ce3+ is strongly nonlinear. To explain this effect, the suggestion is made that Ea is the energy distance between the excited 5d1 level of Ce3+ and a defect level located between the 5d1 level and the bottom of the conduction band and arising from the Ga3+ ion perturbed by the nearest neighboring Ce3+ ion. The elec- trons thermally released from the excited Ce3+ ions are suggested to be trapped at the perturbed Ga3+ ions resulting in the appearance of electron Ga2+ centers. In spite of the fact that the paramagnetic Ga2+ ions were not detected by EPR, the process described above has been found for Fe3+ impurity ions, namely, the electron transfer from the 5d1 excited level of Ce3+ to Fe3+ is directly detected by EPR.
