Polyvinylpyrrolidone (PVP) was successfully used as a capping reagent in an aqueous solution to prepare zinc oxide semiconductor nanoparticles (ZnONPs). Transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR), and UV-visible spectroscopy were used to determine the effects of PVP concentrations on the morphology, crystallinity, and spectroscopic properties of (ZnONPs). TEM results showed ZnONPs in various shapes (spherical, cubic, hexagonal) and sizesdoi:10.21203/rs.3.rs-1750601/v1 fatcat:473coejehbadtn3jurxqshsrtm
