Synthesis and characterization of copper oxide NPs (CuO)

This thesis aims to synthesize CuO nanoparticles by a facile hydrothermal (autoclave) method, which is a low-temperature technique that can produce high-quality large-powder nanostructures with high homogeneity, and then examine their structural, morphological, electrical, and optical properties. CuO nanoparticles have various applications in fields such as solar cells, energy storage devices, super conductors, and gas sensors. CuO is also low-toxic, environmentally friendly, cheap, and abundant. The fabricated CuO nanoparticles were characterized by X-ray diffraction (XRD) show that CuO NPs have Monoclinic structure, scanning electron microscopy (SEM) results support XRD, UV-vis absorbance shows absorption edge at wavelength 330 ~ 340, and photoluminescence spectra (PL). seems that there are three peaks, a broad emission peak in the visible range appeared at 461 nm, 512 nm, and 704 nm.
