Synthesis and characterization of Sb-doped SnO2-(CeO2-TiO2) composite thin films deposited on glass substrates for antistatic electricity and UV-shielding

Sb-doped SnO2 (ATO)-(CeO2-TiO2) thin Films were deposited on glass substrates using the mixed solution including CeO2-TiO2 precursor and ATO particles by sol-gel dip coating process. ATO particles were prepared using low-temperature hydrothermal process. The mixed molar ratio of ATO to (CeO2-TiO2) vs the properties of CeO2-TiO2 thin film was investigated. The optical properties of the films were characterized by UV-visible transmission and infrared reflection spectra, the sheet resistance of ATO particles and films were measured by rubber sheeter (MYI-50) and four-point probe (HisuperGroup Inc, SDY-5), the surface morphology and structure of the films were analyzed using 3D Digitale Mikroskop and X-ray diffraction (XRD), respectively. The results showed that the ATO precursor solution lost weight completely at about 500 °C, and the ATO particles was obtained, which indicated the same rutile lattice structure as SnO2. The glass substrates coated with ATO-(CeO2-TiO2) thin films showed better properties in antistatic electricity (104-106 Ω/▭), shielding UV (almost 100%), visible light transmission (70%) and infrared reflection (>30%).
