Zn(II) Di‐isobutyldithiocarbamate Complex Enabled Efficient Synthesis of Au/ZnS Nanocomposite Core‐shell in One Pot

Abstract

AbstractHere, we demonstrate a one pot synthesis of gold/zinc sulphide (Au/ZnS) core‐shell type composite nanostructure via thermal decomposition of single molecular precursor Zn(II)di‐isobutyldithiocarbamate complex. In these Au/ZnS core‐shell type hybrid nanostructures where ZnS quantum dots are assembled onto Au nanoparticles surface were prepared via a facile and reproducible approach under mild conditions. The crystalline nature and interface of these Au/ZnS core‐shell type composite nanostructures were confirmed by X‐ray powder diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), High‐resolution transmission electron microscopy (HRTEM) and inverted TEM images. Here Zn(II)di‐isobutyldithiocarbamate complex acts as ZnS source as well as reducing and stabilizing agent for Au0 at their nanoscale range by coating in the reaction medium.
