A Study Of Tio2 Thin Film Using Sol-Gel Method
AbstractThis paper reports on a study of titanium dioxide (TiO2) thin films. TiO2 thin films were prepared by sol-gel method using nano- TiO2 powder dissolved in Isopropanol solution. The nano- TiO2 powder was previously extracted from local mineral waste which is known as ilmenite. Using the aqueous solution containing 0.1g of nano-TiO2 powder, several acids which are acetic, hydrochloric (HCI) and nitric were used to study its effects. Each sample was mixed with Triton X-100. Using spin-coating technique the thin films were deposited with 1000 r.p.m for 30s and 3000 r.p.m for 60s. The thickness of each sample was characterized using KL surface profile. The surface topologies and roughness were characterized by an XE-100 Park system atomic force microscope (AFM).The optical property was characterized with a Lambda-750 Perkin Elmer ultra violet-visible spectrometer (UV-Vis). It was found that by using nitric acid more uniform and transparent TiO2 thin film has been produced.
