Abstract
The Cupric oxide (CuO) nanostructures and Fe doped CuO nanomaterials are synthesized by microwave irradiation method. The effect of Fe doping on the crystal structure, band gap and optical properties of synthesized samples were characterized by using x-ray diffraction, ultraviolet-visible spectrometer, photoluminescence spectrometer and Fourier transform infrared spectrometer. X-ray diffraction study confirms the size of the particle in nanometer. The optical band gap calculated from UV–Vis absorption spectrum, reveals the change in band gap energy due to the presence of dopants. The photoluminescence spectrum suggests that Fe doped CuO nanoparticles may be used in optoelectronic devices. The functional group analysis carried out by Fourier transform infrared spectroscopy confirmed the substitution of Fe in the samples.
