Low Transmittance of Anatase Titanium Dioxide (TiO2) Prepared via Doctor Blade Technique

Abstract

The effect of deposition layer on the physical, optical and electrical properties of TiO2thin film that were deposited on glass substrates by doctor blade was studied. xray diffraction pattern showed no disruption of crystal and the material is confirmed anatase TiO2. The thicknesses of the thin films increased as the deposition layer increased. FESEM images show crack-free film when the deposition layer was increase. The optical transmittance showed a very high transparency thin films where the readings decreases from 5% to 0% in the visible region. I-V results indicate that the current does not shows any trend of increasing or decreasing from 1 layer to 5 layers' deposition. However, layer 1 exhibited the highest current with 300×10−9 A.
