Abstract

A single source precursor zinc complex: Zn(phenyl alanine dithiocarbamate)2 have been chosen to synthesize ZnS nanostructures by solvothermal route. Zn(phenyl alanine dithiocarbamate)2 has been synthesized from ligand L-phenyl alanine dithiocarbamate (PHEDTC) by simple mixing. Crystalline texture, phase analyses and size-shape analyses of prepared ZnS nanostructures have been carried out by XRD and TEM, respectively. The hexagonal structure ZnS nanocrystals of various morphologies (nanosheets, nanotriangles and nano pyramids) have been confirmed by diffraction and electron microscope studies, respectively. UV-vis. absorption studies have been carried for the detailed optical analyses. Photoluminescence (PL) study was carried out to check luminescence of synthesized ZnS nanostructures in electromagnetic spectrum. It has been reported that morphology of synthesized nanostructures strongly depends upon the precursor complex prepared from ligand; L-phenyl alanine dithiocarbamate. Photo-catalytic potential of the ZnS nanostructures has been observed in visible light using MB dye as a pollutant in water medium.
