    A novel approach to enhancement of surface properties of CdO films by using surfactant: dextrin
    (Taylor & Francis Ltd, 2015) Sahin, Bunyamin; Bayansal, Fatih; Yuksel, Mustafa
    We studied the effect of an organic surfactant, dextrin, concentration on structural, morphological and optical properties of nanostructured CdO films deposited on glass substrates by using an easy and low-cost SILAR method. Microstructures of the nanostructured CdO films were optimized by adjusting dextrin concentration. XRD, SEM and UV-Vis Spectroscopy were used to study phase structure, surface morphology and optical properties of CdO films. Furthermore, effects of dextrin concentration on the surface roughness characteristics of CdO samples were reported. The results showed that the presence of organic surfactant highly affected the physical properties of CdO nanomaterials.

    Preparation and Characterization of Zn x Cu(1-x)O Composite Films on Glass Substrates Through SILAR Processing
    (Springer, 2015) Bayansal, Fatih; Sahin, Bunyamin; Yuksel, Mustafa
    CuO composite thin films with and without Zn-doping are deposited onto glass substrates by the SILAR method. All the films are characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), UV-Vis spectrophotometry, temperature dependent dc conductivity, and X-ray diffraction (XRD) measurements. SEM results show that the particle size decreases from 27 to 16 nm with increasing Zn-doping. EDX analysis evidences the amount of Zn in CuO films, which increases with increasing Zn concentration in the growth solutions. Transmittance, optical band gap, and activation energy values of the films are found to be increasing from the UV-Vis and temperature dependent dc conductivity measurements with increasing Zn-doping. It also is found from the XRD patterns that mean crystallite size of the films decreases from 18.94 to 13.70 nm with increasing Zn-doping. Moreover, increase in Zn concentration results peak shifts to lower 2 theta values. (C) The Minerals, Metals & Materials Society and ASM International 2015
