Cathodoluminescence and X-Ray Luminescence of ZnIn2S4 and CdGa2S4 Single Crystals

Year: 2022

Type: conference-paper

Abstract: Zinc thioindate and gallium thiogallate single crystals were grown by a chemical vapor transport method. The cathodoluminescence and X-ray luminescence spectra of ZnIn 2 S 4 and CdGa 2 S 4 single crystals were studied. From cathodoluminescence spectra of ZnIn 2 S 4 at low temperatures the forbidden gap width of (2.96 ± 0.02) eV at 80 K and optical depth of the deep acceptor level E A = (E V + 0.30) eV were determined. In the X-ray luminescence spectra of CdGa 2 S 4 a single emission band is observed with an energy maximum at 2.14 eV and a slope within the high-energy range at approximately 2.34 eV identified as optical transitions of donor-acceptor type.
