Zinc oxysulfide -Zn(O, S) is one of the prospective materials for substitution of conventional CdS buffer layer in complete optoelectronic devices due to its optimal bandgap and low toxicity. In this work Zn(O, S) thin films have been prepared by one-step pulsed laser deposition technique. The films with a thickness of 650 nm were deposited onto the FTO/glass substrates at different substrate temperatures from room temperature to 400 degrees C. Zn(O, S) layers were characterized by means of scanning electron microscopy, energy dispersive spectroscopy, Raman, X-ray diffraction, UV-vis spectroscopy and Van der Pauw technique. It was found, that obtained Zn(O, S) layers are mainly polycrystalline, highly uniform, transparent, electrically conductive and demonstrate good adhesion to the FTO/glass substrates. In addition, we show that elemental composition of PLD Zn(O, S) films depends on the substrate temperature. For the first time high quality single phase conductive Zn(O, S) layers were prepared by one stage PLD in high vacuum at relatively low temperature 200 degrees C without any post treatment. The properties of prepared Zn(O, S) films suggest that these films can be applied as buffer layer in optoelectronic devices. (C) 2017 Elsevier B.V. All rights reserved.
