Absorption spectra of Co(2+) in AgInS2 orthorhombic single crystals

The optical absorption spectra of AgInS2:Co(2+) single crystals grown by chemical transport reaction using iodine as a transporting medium were studied at 6 K. The peaks can be explained by the transitions of Co(2+) in the T(sub d) symmetry with the spin-orbit coupling, which means that the deviatio...

Description
Summary:The optical absorption spectra of AgInS2:Co(2+) single crystals grown by chemical transport reaction using iodine as a transporting medium were studied at 6 K. The peaks can be explained by the transitions of Co(2+) in the T(sub d) symmetry with the spin-orbit coupling, which means that the deviations of the atomic sites from those of the ideal wurtzite structure can be considered negligibly small. Consideration of both the crystal field parameters and the electronegativity difference between atoms may indicate that Co atoms substitute In atoms. (Author)
