Abstract
In this study, we reported a simple, clean and green synthetic process of copper nanoparticles from copper sulphate using Cinnamomum tamala (tejpatra) leaf extract. Formation of copper nanoparticle was examined at regular intervals using ultraviolet visible (UV-Vis) spectroscopy. X-ray diffraction (XRD) and transmission electron microscopy (TEM) revealed the crystalline nature and morphology of the produced nanoparticles respectively. The result of Fourier transform infra-red (FTIR) spectroscopy of these nanoparticles indicated the presence of a few organic moieties associated with capping and surface stabilization of the colloidal particles. Thin film of these biogenic copper nanoparticles was prepared and further exposed to various voltage levels to study its conductive behaviour and the result showed the semiconducting nature of the thin film at room temperature.
