Abstract

Honey, a common natural product contains biomolecules responsible for the reduction and stabilization of nanoparticles. In this paper, we have demonstrated the cost effective, eco-friendly green synthesis of zinc sulphide nano/microstructures by chemical co-precipitation method using honey as the stabilizing agent. The structural and morphological properties of zinc sulphide nano/microstructures were studied by X-ray diffraction, scanning electron microscopy, energy dispersive X-rays spectroscopy and Fourier transform infra-red spectroscopy. Comparative studies on the synthesized zinc sulphide nano/microstructures before and after calcinations (700 0C) were carried out using UV-visible and photoluminescence spectroscopy. UVvisible spectroscopy data shows that there is blue shift of the absorption peak for the synthesized zinc sulphide nano/microstructures sample (Eg=4.08 eV) and red shift of the absorption peak for the calcinized (700 oC) sample (Eg=3.37 eV) with respect to bulk sample. X-ray diffraction data reveals that phase transformation has occurred after calcination from cubic zinc blende structure to hexagonally packed wurtzite structure and it is also partially oxidized to zinc oxide.
