The experimental and theoretical studies of the optical properties of pure α-ZnAl 2S 4 and α-ZnAl 2S 4:V 3 crystals were carried out. The ab initio and crystal field calculations of the structural and optical properties of α-ZnAl 2S 4:V 3 were compared with the corresponding experimental data. It was shown that the lowest vanadium 3d states are located at about 1.36 eV above the valence bands top. The complete energy level scheme of the α-ZnAl 2S 4:V 3 system, which includes the hosts electronic band structure and impurity ions energy levels, was suggested on the basis of the performed calculations. |
