The films were deposited onto glass and ITO-coated glass substrates. The deposited films were observed to be blackish brown in color, well adherent to the substrate, pin-hole free and uniform. The structural, surface morphological and optical properties of the films were carried out by means of X-ray diffraction, scanning electron microscopy and optical absorbance measurement techniques. XRD analysis showed that deposited films are chemically close to chalcocite, Cu2S. The optical band gap was calculated to be 1.5 eV. (C) 2011 Elsevier B.V. All rights reserved.
