Optical and structural investigations of TiO2 multilayers on glass prepared via sol–gel spin-coating technique

Titanium di-oxide (TiO2) multilayer thin films were deposited on glass substrates by using sol–gel spin-coating technique. The TiO2 thin film coatings were varied from two- to six layers and each layers calcinated at 600°C for 1 hour. The prepared samples were characterized by UV–visible spectrophot...

Description
Summary:Titanium di-oxide (TiO2) multilayer thin films were deposited on glass substrates by using sol–gel spin-coating technique. The TiO2 thin film coatings were varied from two- to six layers and each layers calcinated at 600°C for 1 hour. The prepared samples were characterized by UV–visible spectrophotometer (UV–Vis), Fourier transform infra-red (FTIR) spectroscopy and X-ray diffractometer (XRD) techniques. The UV–Vis spectra showed the highest reflectance with the effect of six (6L) layers of TiO2 thin films as compared to the two- (2L) and four (4L) layers of thin films. The XRD patterns revealed the anatase-TiO2 phase with six layers of TiO2 and amorphous-TiO2 nature confirmed by two and four layered films. The obtained results proved that the use of enhanced multilayers (6L) of TiO2 thin films were effectively improved the quality of film crystallinity (8.3 nm) and corresponding optical performance as compared to reduced layers.
