Doped Titanium Dioxide Ti(1-x)pbxo2 (x=0.1,0.3,0.4 wt%)

Abstract

Titanium dioxide is considered one of the most important oxides in international research laboratories due to its distinct characteristics and to study the changes that occur in its physical properties ,the optical properties of powders of titanium dioxide were examined with lead in different ratios (x=0.1 - 0.3 - 0.4 wt%)after being prepared by the solid state reaction method. The results of the infrared spectroscopy showed the optical properties of the pure and lead-doped powders, which are: transmittance T, absorbance A, reflectivity R, obsorption coefficient α,damping coefficient K, refractive index n, optical waevelength L, optical conductivity δ_opt , optical density O.D, and the real dielectric constant ε_r and the imaginary dielectric constant Ɛ_i and the changes that occurred at each dopant percentage compared to the pure sample.
