The phase composition, structural, and morphological features of the nanomaterial were thoroughly characterized by XRD, FTIR, UV-Vis spectroscopy, FESEM, TEM, and EDS. X-ray diffraction confirmed the monoclinic formation of CuO with an average crystallite size of 16.68 nm, while FTIR spectra showed Cu-O lattice vibrations and relevant functionalities of phytochemical capping. Optical studies exhibited a unique absorption peak at 350 nm and direct band gap of 2.7 eV that indicate photocatalytic and optoelectronic potentials. The FESEM images revealed nanoflake petal-like morphology with sizes below 100 nm, while EDS mapping showed the elemental purity of the final product. TEM analysis indicated polygonal particles in the range of 60--90 nm with exposed lattice fringes confirming polycrystalline structure composed of smaller crystallites resolved by XRD. The findings indicate that neem-mediated synthesis is an eco-friendly approach to fabricating CuO nanoparticles with biofunctionalized features possessing well-defined crystallinity, morphology, and surface chemistry, which can be applied in catalysis and drug-plant interactions for potential applications in medicine (via biofunctionalized features), photocatalysis, and antimicrobial activities, contributing to sustainable environmental and pharmaceutical technologies.
