Facile synthesis and characterization of ZnS quantum dots by simple colloidal method

In this work, we show the simple experimental methodology to obtain pure zinc sulphide (ZnS) quantum dots in an aqueous solution. ZnS quantum dots are synthesized by a cost-effective and facile chemical method. The as-prepared quantum dots are observed for different time intervals and have undergone characterisation for their optical, structural and morphological analysis by UV-visible, Photoluminescence, X-ray diffraction, and Scanning Electron Microscopy.
