Y³⁺ doped TiO₂ coatings were successfully prepared on glass slide substrates. The phase structure, optical properties, microstructure and surface properties of the coatings were characterized by using XRD, FT-IR, UV-vis and SEM. The photoinduced super-hydrophilicity and photocatalytic activity of the films were evaluated by the water contact angle measurement and photocatalytic oxidation of Rhodamine B in air, respectively. The results indicated that the doping of Y³⁺ into TiO₂ could improve the hydrophilicity and photocatalytic activity, and TiO₂ thin films doped with Y³⁺ at 2-4 at.% and heat-treated at 450 °C were of super-hydrophilicity. The optimal Y³⁺ content for the photocatalytic activity was 4 at.% and larger film thickness was helpful to reduce the contact angle of the composite films.
