Characterization of biosynthesized zinc sulphide nanoparticles using edible mushroom Pleurotuss ostreatu

Abstract

We report here green synthesis of ZnS nanoparticles using the extract of an edible mushroom (Pleurotuss ostreatu). The obtained ZnS nanoparticles are characterized by X-ray diffraction, energy dispersive analysis of X-rays, scanning electron microscopy, transmission electron microscopy, selected area electron diffraction, UV–Vis optical absorption, photoluminescence and Fourier Transform Infrared Spectroscopy. XRD analysis confirms ZnS nanoparticles have cubic structure and also there is decrease of particle size and increase of dislocation density and strain with increase of amount of mushroom extract. The variation of crystallite size is in conformity with the results obtained from SEM and TEM. UV–Vis and photoluminescence spectra give the characteristic peak for ZnS nano where as Fourier transform infrared spectra confirm the presence of microbial proteins.
