SiO2/TiO2/SiO2 thin films were deposited on glass substrates using an electron beam physical vapor deposition technique.
The structure, morphology, surface composition, surface roughness, optical properties, and hydrophilic properties of the
thin film were investigated. The structure measurement shows that only anatase phase was exhibited in the thin film. In the
TiO2 thin film, the crystals nucleated from the thin films was homogeneous and the average crystalline sizes were 35 nm.
The transmittance spectra of the films revealed transparency in the visible region of the spectrum. SiO2/TiO2/SiO2 thin film
showed better hydrophilicity under irradiation and storage in comparison to SiO2/TiO2 thin film. SiO2/TiO2/SiO2 tri-layer thin
film showed superhydrophilicity which greatly encourages the antifogging function of the film. |
