SYNTHESIS OF ZINC OXIDE QUANTUM DOT, ANTIMICROBIAL ACTIVITY AND APPLICATION FOR WATER TREATMENT
Abstract
Author(s): J. Barman
In the present study we report the synthesis of zinc oxide quantum dot by a chemical route. The obtained nanoparticles were characterized by X-ray diffraction (XRD), FTIR and UV–VIS absorption. Trans mission electron microscopic image as well as XRD studies confirmed the nanometer size particles formation within the polymer matrix. The average particle size was found to lie in the range of 3.7–6.9 nm. A UV-VIS optical spectroscopy study was carried out to determine the band gap of the nanocrystalline ZnS thin film and it showed a blue shift with respect to the bulk value. The synthesized nanoparticles showed tremendous antimicrobial activity and can be used for water purification.
