摘要：

Coating nonmetallic-chalcogenide film material is developed to avoid oxidation and corrosion of the thin films. The chalcogenide part consists of a thin film of Se60Te30S10 prepared by the thermal evaporation technique. On the other hand, the nonmetallic carbon thin film is applied onto the as-plated chalcogenide surface by deposition from an electrically heated carbon rod (arc discharge). The products obtained are characterized with X-ray diffraction and Scanning Electron Microscopy. It is observed an enhancement in crystallinity upon annealing for the as prepared uncoated and coated carbon films is observed. Optical studies reveal that carbon coating influences the optical energy gap, absorption coefficient and refractive index of the Se60Te30S10 thin film. (C) 2014 Elsevier Ltd. All rights reserved,
