Solid-state and solution phase metathetical synthesis of copper indium chalcogenides

Abstract

Copper indium chalcogenides, of the type CuInE₂ (E=S, Se and Te), have been successfully prepared by solid-state and solution phase metathetical reactions of CuBr or CuCl₂ , InCl₃ and the appropriate sodium chalcogenide (Na₂E). The copper indium chalcogenides were analysed by powder X-ray diffraction, scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDXA) and FTIR spectroscopy.
