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

Here, 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 Au-0 at their nanoscale range by coating in the reaction medium.
