Based on recent discovery of high-rate reactive magnetron sputtering, which was a key requirement for production of coating industry, this study focused on enhanced deposition rate of TiO2 films for photo-induce hydrophilic applications. The TiO2 thin films were reactively sputtered, which a pulsed DC source, from high-purity (99.995%) titanium (Ti) target on glass and silicon (100) and wafer substrates. During the deposition, a mesh grid cover was installed on the sputtering source with varying argon gas flow rates. Properties of the TiO2 films were compared between deposition with and without a mesh grid cover. The microstructure of the TiO2 films was studies by grazing-incidence X-ray diffraction (GIXRD) and field-emission scanning electron microscope (FE-SEM). The optical properties were determined by UV-Vis spectrophotometer. The contact angle measurement was used to determine the hydrophilicity of the films after exposing to UV light. For using the mesh grid during film deposition, it was found that the deposition rate of the TiO2 films was increased in oxide mode with a small grain size. In this case, the TiO2 films showed high transparent and good photo-induced hydrophilic properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
