Synthesis of Ag –TiO2 Thin Films by Spin Coating process

Abstract

In this research, Sol-gel technique prepared Ag-TiO 2 nano-composite thin films, which were deposited onto a glass substrate by the spin coating process. The microstructures and chemical ingredients of the obtained thin films were characterized by UV-visible spectroscopy (UV), Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FT-IR). It was discovered that the silver nano-particles completely joined to the TiO 2 matrix, where those nanoparticles distributed uniformly. In this way, the molar percent of the silver nitrate watery solution dominated the morphology of the thin film. Ag-TiO 2 Nano composite is very useful for expanding antibacterial of nanomaterials purpose.
