High transparent sol-gel derived nanostructured TiO₂ thin film

Materials Leters 62 (2008) 361–364

In this investigation, high transparent nanostructured TiO₂ thin film has been prepared by a dip-coating method. The prepared sol was obtained through the hydrolysis of titanium isopropoxide under the selected pH. The transmission of film as an optical parameter was characterized by spectrophotometer. With respect to other experimental results, a high transmission spectrum without any fluctuation in visible wavelength region has been recorded. According to transmission spectrum of film the refractive index and extinction coefficient has been determined. Experimental result has shown that the prepared film has high transmission and good optical parameters. SEM and AFM have been applied for morphology characterization of the film surface.
