Synthesis and characterization of wurtzite ZnS nanoparticles via solvothermal method

Zinc Sulfide has been widely studied due to it‘s component important wide-band-gap (3.6eV) semiconductor materials. ZnS can be prepared in various dimensional such as nanotubes, wires, rods, belts and ribbons, two-dimensional (sheet, plateles, diskettes) and three dimensional like spheres. But there is a few reports on the fabrication of ZnS only with presence thio Schiff-base ligand. ZnS can be prepared via different methods such as irradiation, solvothermal, physical evaporation and surfactant-mediated micro emulsion.In this work a thio Schiff-base-assilsted solvothermal process has been developed to synthesize Zinc Sulfide (ZnS) nanoparticles via the reaction between a metal salt Zn(NO3)2-6H2O and thio Schiff-base N-benzylideneethanethioamide as a new precursor (Fig. 1). XRD and FT-IR spectroscopy were employed to characterize the obtained product. SEM images were used to investigation shape and size of synthesized ZnS. The results of this paper indicate that the shape and size of Zinc Sulfide nanoplates can be controlled systematically by setting certain reaction parameters, such as the reaction temperature and duration and type of solvent. Zinc Sulfide nanoparticles with different morphology and size have been successfully prepared.
