Abstract


In this study, we report the synthesis and optical properties of flower-shaped ZnO which is fabricated successfully using polyvinylpyrrolidone (PVP) as capping agent by wet chemical method at temperature 600C. The structures and morphologies of flower-shaped ZnO is characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM) for nonlinear dynamical study of the system of particles. The studies of SEM and TEM have confirmed flower-shaped structure of the ZnO. The UV-vis absorption spectroscopy of the synthesized sample indicates the presence of blue shift. FTIR analysis shows the characteristic absorption of the Zn-O bond. It has been observed in room temperature photoluminescence (PL) spectroscopy of the sample exhibits emission peaks at near band edge (NBE) along with a weak blue emission peak. It is found from the present study that the phenomenon of flower-like microstructure is based on the size and shape of the particles as well as their aggregated forms. Moreover, their optical properties predict the factors responsible in inhibiting microorganisms for which it may lead to some biological applications.
