Studying the Structure and Optical constants Properties of nanoparticles prepared by hydrolysis of titanium oxide deposition by drop casting method

Abstract

Thin films of (TiO₂) with (1µm) thickness have been prepared by Drop casting technique after dissolving titanium chloride with distilled water with drops of concentrated hydrochloric acid on glass substrate with (2.5 * 2.5 ) cm² dimensions . Optical properties include recording of transmittance and calculate absorptance spectra for prepared films in wavelengths range  (370-900)nm. Optical constants sach as: reflectance, extinction coefficient, refractive index, real and imaginary parts of the dielectric constant and the electrical conductivity
