Nanostructured Anatase Titania Thin Films Prepared by Sol-Gel Dip Coating Technique

Anatase titania thin films were deposited on glass substrates. The substrates were dipped matched dipped into the solution under vigorous stirring. The films were dried at room temperature. Oley amine (OM) was used as a surfactant in the synthesis part and it was vigorously stirred with titanium isopropoxide (TIP) at room temperature. The film samples were annealed at 550\(^\circ\)C for 15 hours. X-ray diffraction (XRD) and Raman spectroscopy were used to study the structural properties of samples. The optical properties of samples were investigated by means of ultraviolet visible (UV vis) spectroscopy. XRD results illustrated the amorphous structure and pure anatase phase of TiO\(_2\) for as deposited and annealed thin films samples and these results were further confirmed by Raman spectroscopy. UV-visible corroborates the energy band 3.26 eV and 3.22 eV for as prepared and sintered TiO\(_2\) thin films which simply refers to the change in crystal structure of anatase titania. Furthermore, both samples had high transmittance; almost 78-86%.
