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

The effect of deposition layer on the physical, optical and electrical properties of TiO
₂
thin film that were deposited on glass substrates by doctor blade was studied. X-ray diffraction pattern showed no disruption of crystal and the material is confirmed anatase TiO

. 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
