Synthesis and Characterisation of ZnS Nanoparticles

Parvathy P, Shabna S

Abstract: ZnS nanoparticles are prepared by Coprecipitation method using EDTA (Ethylenediaminetetraacetic acid) as capping agent. It is characterised by UV-Visible spectra, X-ray diffraction studies. UV Visible absorption spectra are used to find the optical band gap and the value obtained has been found to be 4.5eV. The particle size of nanoparticles calculated from XRD pattern has been approximately 4 nm.
