Green Synthesis and Characterization of ZnS nanoparticles

The development of green synthesis route through biological method for the synthesis of nanoparticles using plants have received attention in the recent times as it is environment friendly and economical method. ZnS nanoparticles have been prepared using glucose both as capping agent and stabilizer. The obtained ZnS nanoparticles are studied by X-ray diffraction (XRD), Energy dispersive analysis of X-rays (EDAX), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Selected area electron diffraction (SAED), UV-vis optical absorption, Photoluminescence techniques (PL) and Fourier Transform Infrared Spectroscopy (FTIR). The mean particle size of the ZnS nanoparticles is found to be 5.8 nm. The XRD analysis confirms the cubic and crystalline nature of the synthesized sample which is in good agreement with SAED pattern. Also, EDAX pattern confirms the presence of Zinc and Sulfur. . UV-vis spectra show that the absorption peaks exhibit blue shift from the bulk. The PL investigation revealed the recombination mechanism in ZnS nanoparticles. FTIR spectra confirm the presence of glucose as capping agent.
