Synthesis of Zinc Oxide Nanostructured Thin Film by Sol- Gel Method and Evaluation of Gas Sensing Properties
Ethanol (C2H6O) sensitivity of zinc oxide (ZnO) thin film has been studied in present work. Semiconductor thin films of zinc oxide (ZnO) were deposited onto alkali-free glass substrates by the sol–gel method and dip-coating technique. The ZnO sol was synthesized by dissolving zinc acetate dehydrate in ethanol, and then adding Tetra ethanol-amine. The as-coated films were preheated at 150 ºC fo...
متن کاملAl Doped ZnO Thin Films; Preparation and Characterization
ZnO is a promising material suitable for variety of novel electronic applications including sensors, transistors, and solar cells. Intrinsic ZnO film has inferiority in terms of electronic properties, which has prompted researches and investigations on doped ZnO films in order to improve its electronic properties. In this work, aluminum (Al) doped ZnO (AZO) with various concentrations and undop...
متن کاملEvaluation of Photocatalytic Activity of Fe Doped TiO2 Thin Film Prepared by sol-gel hot dip-coating
The application of Fe–TiO2 photocatalysis using sol–gel method by hot–dipping technique was investigated. Then, the influences of fabrication parameters, molar ratios of Fe to TiO2, the sol temperature, poly ethylene glycol (PEG) content and the number of dipping cycles on the photocatalytic activity in visible light region were mainly studied. The experimental results revealed the sample with ...
متن کاملOrganic Thin Film Transistors with Polyvinylpyrrolidone / Nickel Oxide Sol-Gel Derived Nanocomposite Insulator
Polyvinylpyrrolidone / Nickel oxide (PVP/NiO) dielectrics were fabricated with sol-gel method using 0.2 g of PVP at different working temperatures of 80, 150 and 200 ºC. Structural properties and surface morphology of the hybrid films were investigated by X- Ray diffraction (XRD) and Scanning Electron Microscope (SEM) respectively. Energy dispersive X-ray spec...
متن کاملEffects of UV irradiation treated polycarbonate substrates on properties of nanocrystalline TiO2 sol-gel derived thin films
In this study, in order to achieve effective coating of the homogeneous titanium dioxide (TiO2) thin film, UV irradiation pre-treatment was carried out to activate PC surfaces before coating. Sol-gel-based nanocrystalline TiO2 thin films were prepared by employing tetrabutyl-titanate as a precursor. Nanocrystalline TiO2 thin films were deposited by sol-gel spin coating on the treated substrates...
