The synthesis of Ag/TiO₂ thin film was carried out by the sol-gel spin coating method using ITO glass as a substrate in a short period of stirring time, which is less than 25 min. The produced films were annealed in a furnace at 500° for 1 h. Various concentrations of AgNO₃, from 0.1 to 0.9 M, were added. The as-prepared films were characterized using X-ray diffraction, scanning electron microscopy, and atomic force microscopy. The results indicate that all films showed a single phase of anatase, TiO₂. Ag/TiO₂ thin films with 0.1 M of AgNO₃ solution show that the elements form networks connecting Ag/TiO₂ microstructures forming a porous, consistent, and continuous layer on the substrate surface.
