| Abstract | ||
| A theoretical study shows the effect of the Gallium antimonide (GaSb) shell on several visual properties of the Iron (III) oxide (ferric oxide) Fe2O3 core as a nanowire using the Mie-Lorentz Scattering theory. The thickness of GaSb shell was fixed at around 20 nm with Fe2O3 core diameter of 20 nm. The study indicated that the nanowires of the Iron (III) oxide core have transmittance approximately 95% in the visible spectrum. Absorbance and low absorption coefficient in the Infrared (IR) are observed. Electronic transitions of the allowed direct type by the coaxial nanowire and reducing in the energy gap after adding the shell around the Fe2O3 to energy gap about 1.7 eV are also seen. | ||
