摘要：
The transmittance spectra in the region of the fundamental absorption edge are studied at 80 and 295 K for the single-crystal compounds FeIn2S4 and In2S3 and (FeIn2S4)(1 - x) (In2S3) (x) alloys grown by the Bridgman method. From the experimental spectra, the band gap of the FeIn2S4 and In2S3 compounds and (FeIn2S4)(1 - x) (In2S3) (x) alloys is determined. The dependence of the band gap on the composition parameter x of the alloy is constructed. It is established that the band gap nonlinearly varies with x and can be described by a quadratic dependence.
