Optical Study to Doping Carbon with TiO2 that Utilizing in Thermal Concentration

Abstract

The optical properties of TiO2/C in the district from (200-2000 nm) were examined by setting up the composites with wt. % concentration. The optical information evaluated and translated regarding the hypothesis of phonon-assisted direct electronic change; it is watched that the energy is influenced by doping sort of mineral composite utilized. The doping manufactured powders were examined through data analysis to validate the presence of these elements. This investigation for the influence of TiO2 was an addition on the microstructure of the carbon and electrical behavior of the composite was detected, this doped was gotten in a dry place at ambient temperature and its effect was studied from the physical properties of the energy gap. The optical measurement of the specimen was measured as a component of wavelength (λ), absorptivity that exhibit good results to absorb the solar energy for selective surfaces.

Spectrally selective coating of nanoparticles (Co3O4:Cr2O3) incorporated in carbon to captivate solar energy

“…The values of E g for the specimens (F, G, and H) ranged between 2.9 and 3.9 eV, and are attributed to the content of Cr 2 O 3 , but the specimens (I and E) ranged between 3.05 and 3.8 eV, attributed to the content of Co 3 O 4 concentration. The results of E g are highly consistent with previous research . The values of E g were calculated according to the above equations and the results are shown in Table .…”
