Rezumat

In the present work we report on the combined experimental and theoretical studies of the optical properties of α-ZnAl2S4 spinel doped with V3+ ions. The studied samples (both with and without vanadium) were grown by the chemical vapor transport method. The undoped ZnAl2S4 crystals were colorless, whereas the V-doped samples were brown. The optical absorption spectra for both un-doped and V-doped α-ZnAl2S4 were recorded at room temperature using a Perkin Elmer Lambda 900 spectrometer in the wavelength range 300–1700 nm. Theoretical analysis of the obtained spectra was performed using both the exchange charge model of crystal field (CF) [1] and ab initio-based CASTEP module [2] of Materials Studio. An essential feature of the performed analysis is that it allowed for a reliable estimation of the position of the lowest V3+ energy level (1.36 eV above the valence band’s top, [3]) with a subsequent positioning of all excited states of V3+ ions, which were derived from the CF calculations. The obtained results are summarized in Figure 1, which shows the experimental and calculated absorption spectra of ZnAl2S4:V3+ along with the band structure of the host with superimposed energy levels of impurity.
