Characterization of CuO/Polystyrene nanocomposite deposited by spin-coating technique



  1. Laboratory of Crystallography, Department of Physics, University Freres Mentouri, Algeria


This work presents the results of an investigation on the structural and optical properties of CuO/polystyrene (CuO/PS) nanocomposite, prepared by a simple insertion of CuO nanoparticles into polystyrene (PS) matrix. CuO nanoprticles have been synthesized by a hydrothermal method, and thin films of CuO/PS nanocomposite have been deposited on glass substrate by spin–coating technique. X-ray diffraction and atomic force microscopy (AFM) have been used to study the structural and morphological properties of CuO/PS nanocomposite thin films. XRD have demonstrated the incorporation of monoclinic CuO nanoparticles in PS matrix and AFM micrographs have shown a homogeneous dispersion of CuO particles. The size of CuO particles was found to lie in the range 08.26 – 20.80 nm. FT-IR and Raman spectroscopy exhibit vibrational modes corresponding to the CuO monoclinic phase. The UV–visible absorption measurement indicates that the band gap energy of the CuO/PS nanocomposite thin films is 3.31 eV, and shows a significant blue-shift in the band gap energy of CuO, which is due to the quantum confinement effect performed by the CuO nanocrystals. Room temperature photoluminescence spectrum has shown that the insertion of CuO nanoparticles in PS matrix enhances the luminescence, in the visible range, of prepared CuO/PS nanocomposite..
