Abstract

ZnS: CuS Nanocomposite flexible Thin films have been prepared by simple and low cost Chemical bath deposition (CBD). Additionally, the effect of dipping time of the ZnS Thin films into the copper chloride solution on structural, morphological, optical, and photocatalitic properties of the ZnS: CuS films have been investigated by XRD, FE-SEM, TEM, and UV-vis spectroscopy. XRD and TEM results confirmed formation of the flexible ZnS: CuS Nanocomposite films which consist of nanocrystals with less than 10 nm in diameter. FE-SEM images indicate that ZnS: CuS Thin films consist of high compactness particles with good adhesion to the flexible substrates. Energy band gap of the films were decreased by increasing amount of Cu in the films which it could be related to the formation of the CuS phase. The prepared ZnS: CuS Nanocomposite Thin films showed a photocatalytic activity in degradation of Rhodamin B dyes (water pollutant). By increasing amount of Cu in the films and exposure time in the visible light, degradation percentage of the Rhodamine B dyes were increased because of the decrease in recombination of the electron – hole pairs. During investigation of the photocatalytic activity of the layers, due to strong adhesion to the substrate, it was not necessary to homogenize the solution and centrifuge for extracting nanoparticles from the solution.
