| Abstract | ||
| In this research, a theoretical investigation of the effect of shell (Si, Pt, Ni) on some optical properties for the core of Iron oxide Fe2O3 as a coaxial nano wire using the scattering approximation (Mie-Lorentz Scattering theory). Thickness value of (Si, Pt, Ni) shell was limited to about ( 5 nm) and Fe2O3 core diameter of 20 nm. The work showed that the coaxial nano wires have a very high transmittance in the visible spectrum region. The values of transmittance are more than 95% for Fe2O3 core only and (Fe2O3-Si) core-shell. In construct, the compound of fe2O3-Pt and fe2O3-Ni show a low transmittance in the same region. Absorbance and low absorption coefficient of Fe2O3 and fe2O3-Si in the infrared spectrum with the appearance of two absorption edges of Fe2O3-Si. The energy gap decreases after adding (Si, Pt, Ni) shell as this in a good agreement with some experimental researches where the values of the energy gap for (fe2O3-Si), Fe2O3-Pt, and Fe2O3-Ni were (2.4, 2, 1.7) ev respectively. | ||
