Abstract

Homogeneous single crystals of CuIn7S11 having diameters of ∼14 mm and ∼40 mm long were grown by the vertical Bridgman technique. The composition and structure of the single crystals were determined. Transmission spectra in the region of the intrinsic absorption edge were studied In the single crystals at temperatures in the range from 20 to 300 K. The transmission spectra were used to determine the bandgap width and its value as a function of temperature. Photoluminescence spectra of the crystals were studied in the range from 20 to 130 K. The nature of photoluminescence bands is discussed.
