Abstract
FeIn2S4)x · (AgIn5S8)1–x alloy single crystals are grown in the entire region of composition parameters x by the Bridgman method. It is established that the single crystals crystallize in the cubic spinel structure. Nuclear γ-resonance spectroscopy is used to study the local configurations of iron ions in the structure of (FeIn2S4)x · (AgIn5S8)1–x alloys. From the transmittance spectra in the region of the fundamental absorption edge, the band gap (Eg) of the alloys is determined, and its concentration dependence is constructed. It is shown that Eg nonlinearly varies with x.
