Abstract

The exchange charge model of the crystal field is applied to calculate the complete energy level scheme of the Cr4+ ions in Y3Al5O12 using $D_{2d}$  symmetry at the Cr4+ position. Mixture of the spin-triplet states arising from the  $^{3}F$ and $^{3}P$ terms of the 3d 2-electron configuration is shown to have a profound effect on the energy levels sequence. Large splittings of the orbital triplets originating from the “parent” Td symmetry are explained by large contribution of the low-symmetry component of the crystal field. Huang-Rhys parameter and effective phonon energy are evaluated from the experimental spectroscopic data available in the literature. Temperature-dependent probability of the nonradiative transition between the ground and first excited states is drawn; the emission band shape is obtained using the single configuration coordinate model.
