Synthesis and characterization of hierarchical ZnS architectures based nanoparticles in the presence of thioglycolic acid

Spherical ZnS based nanoparticles (hierarchical architectures) were successfully synthesized using Zinc bis(salicyle aldehitato), Zn(Sal)(2), thioacetamide (TAA) and thioglycolic acid (TGA) as Zn2+, sulfur source and capping agent, respectively. The hierarchical ZnS structure was produced from the self-assembly of nanoparticles with diameters of 21 +/- 4 nm. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and Fourier transform infrared (FT-IR) spectra. The influence of temperature on the morphology of the products was also investigated. The possible formation mechanism and optical properties of these architectures were also reported.
