Abstract :
The wet chemical method has been implemented to synthesize CuO nanostructures at 1000C. The monoclinic phase structure of CuO nanostructures has been affirmed by X-ray Diffraction (XRD) pattern. Crystal size and dislocation density of the nanostructures have been calculated from XRD data. UV-visible absorption spectra have been used to estimate band gap of the prepared CuO nanostructures. The refractive index and dielectric constant of CuO nanostructures have been calculated from band gap which shows an increase with the decrease of the band gap. Field Emission Scanning Electron Microscopy (FESEM) has been used to inspect the crystals’ surface morphology

Key-Words / Index Term :
