Description
Summary:The S+Ce co-doped TiO sub(2) nanocomposite films deposited on glass substrate had been synthesized by the sol-gel dip-coating method. The as-synthesized samples were characterized using X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and ultraviolet-visible (UV-vis) absorption spectra analysis technologies. The surface morphology and surface chemical composition of the S+Ce co-doped Tio sub(2) nanocomposite film had been primarily investigated. The results shows that the properties of doped TiO sub(2) thin films with different ions have close relations with the intrinsical properties of S and Ce doped ions, the absorption edge shifted towards visible light region and the water contact angle of the surface of the nanocomposite films with the water droplet was only 6[degrees], indicating that the S+Ce co-doped TiO sub(2) nanocomposite film showed promising applications in the self-cleaning and other potential fields.
