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.
