By using Ultraviolet visible (UV\u2013vis) spectroscopy, we observe a characteristic peak at 376\u2009nm that indicates the presence of ZnO nanoparticles, and in addition, the appearance of green color confirmed the presence of CuO nanoparticles in colloidal solutions. An analysis of Rietveld refined powder X\u2010ray diffraction (PXRD) provides insight into the novel crystalline structure of Zn\u2010astrakanite. It was found from the Rietveld refinement results that the synthesized nanocomposite composed of CuO, Zn\u2010astrakanite, and ZnO crystalline phases with compositions 56.26%, 31.49%, and 12.26%, respectively. The green color appearance of the synthesized nanocomposite in colloidal solution was due to the presence of CuO nanoparticles as a major composition and surface plasmon resonance (SPR) characteristic. As revealed by scanning electron microscopy (SEM) analysis, nanoparticles have blade\u2010like morphologies due to ZnO and some randomly shaped crystallites. Fourier transform infrared spectroscopy (FTIR) analysis provides functional information about the synthesized compound, and we detected CuO and ZnO nanocomposites by observing the metal oxide fingerprint regions at 523\u2009cm\n                    <jats:sup>\u22121<\/jats:sup>\n                    and 472\u2009cm\n                    <jats:sup>\u22121<\/jats:sup>\n                    .
