Abstract: In
this work, the sol-gel dip coating technique was used to prepare titanium
dioxide thin
films onto glass substrate with different annealing temperatures, and the
effects of annealing temperatures on optical properties of thin films were
investigated. Optical constants such as optical band gap and thicknesses of thin
films were determined from the measured transmittance spectra in wavelengths
between 300 and 1100 nm. Calculations on the annealed thin films showed that, as
the annealing temperatures varies, optical band gap ranges from 3.33 to 3.69 eV,
thickness ranges from 48 to 375 nm and transmittance ranges from 81% to 98% in
the visible region.
