Study of the effect of thickness on electron transitions of titanium oxide films. TiO2 prepared by pyrochemical deposition

Abstract

TiO2 titanium oxide thin films were prepared by thermal chemical deposition.
on bases of borosilicate glass at a temperature (420 o C). The diffraction pattern results showed

X-rays The prepared films have a polycrystalline structure.
The study included a spectral recording of the absorbance and transmittance of different fishes of
Membranes at the wavelength range (300-900) nm and calculating the absorption coefficient and gap
energy for all transitions. The results showed the effect of changing the membrane thickness on the transitions.
