ABSTRACT

AgIn₁₃S₂₀ single crystals were grown by the vertical Bridgman method. The grown crystals composition was determined by X-ray spectroscopy analysis; the crystal structure was determined by X-ray method. It was shown, that AgIn₁₃S₂₀ compound crystallize in the cubic spinel structure. The band gaps of the obtained single crystals were estimated from transmittance spectra in the temperature range of 10-320 K. The band gap values decreased with temperature.
