Description
Summary:The effect of Cerium on the properties of the multi-functional SiO2-TiO2:Ce3+ nanocomposite films are shown in this paper. The multi-functional SiO2-TiO2:Ce3+ nanocomposite film was synthesis by a sol-gel method and coated several layers on a glass substrate by a spin-coating technique. The bonding was indicated in the obtained film that Si-O-Si and Si-O-Ti bonding, which are characteristics that bonding in the SiO2-TiO2 matrix by the FT-IR spectrum. The TiO2 crystal in the anatase phase and SiO2 in the amorphous phase of the nanocomposite film was determined by X-ray Diffraction. When increased doping of Ce3+, the prepared films have a high transmittance in the visible light (from 84.5 to 88.3%, 400 – 800 nm), the red-shifted of the absorbance edge in UV(A) region (from 355 to 390 nm), and the optical bandgap is narrowed. Particularly, the SiO2-TiO2:6%Ce3+ film has the transmittance by 88.3% in the visible light (400 – 800 nm), absorbance in the UV(A) light (390 nm), and performance the super-hydrophilic with/without thermal and UV(A) light. Thus, the multi-functional SiO2-TiO2:6%Ce3+ nanocomposite film could have a potential to use as the protective high transmittance film to avoid the UV-A light and exhibits a super-hydrophilic on the material surface such as glasses, photovoltaic devices, window panels.
