Microwave assisted synthesis of highly luminescent ZnS nanostructures using zinc dithiocarbazic complex chemical route

Abstract

Bis(parahydroxyacetophenonebenzyldithiocarbazate) zinc(II) and bis (acetophenonebenzyldithiocarbazate) zinc(II) complexes have been synthesized. Zinc sulphide nanostructures were obtained from both complexes at different deposition temperatures using microwave assisted chemical route. The surface morphology of as-prepared ZnS nanoparticles were obtained using X-ray diffraction (XRD), transmission electron microscopy (TEM) and high transmission electron microscopy (HRTEM). Particles with spherical shape are shown in the TEM images of these samples. The optical properties of the particles studied by UV–Vis and photoluminescence (PL) spectroscopy showed evidence of quantum confinement.
