    Influence of Synthesis Conditions and Al doping, on structural and optical properties of ZnOSnO2 thin film
    (University of Oum El Bouaghi, 2021) Benkara, S.; Seghairi, N.; Bouabida, S.; Ghamri, H.
    Zn/Sn nanocomposite deposited on glace substrate by sol gel dip-coating technic, using Zinc acetate and tin chloride as precursors and aluminium chloride as dopping source, absolute ethanol and monoethanolamine (MEA) were used as the solvent and stabilizer, respectively. The quantity of tin in the solution was 0; 25; and 40 at.% Sn, and of aluminium was 0; 0,5; 2; and 4 at.% Al. The films are deposited at two dipping speeds: 100 mm/min and 50 mm/min, and used two dipping cycles: 10 and 5. The structure, optical properties and morphology of nanofilms and the influence of experimental parameters as withdrawal speed and dipping cycles on deposition of ZnO films were studied using X-Ray Diffraction (XRD), UV–vis spectroscopy and optical microscope. The crystalline phase determination from XRD confirmed that the films are composed of hexagonal wurtzite ZnO and tetragonal rutile SnO2 without compound impurities. The doping and dipping speed and cycles effect on optical bandgap is estimated by transmittance spectra.
