Abstract :

In recent years, nanostructured materials have attracted a great deal of attentiondue to their special properties as compared to bulk materials. Semiconductornanoparticles can be synthesized in several methods, including chemical capping,reverse micelles, and hydrothermal. In this research, different methods of ZnSnanoparticle fabrication and the role of the main parameters on the particle sizeand morphology of the samples were investigated by validated methods such asSEM, TEM, XRD and EDAX. In all mentioned methods, decreasing the concentrationof reactants reduces the particle diameter. Also, increasing the rate of addition ofthe reactants reduces the size of the produced nanoparticles. The results of SEMand TEM imaging show that the hydrothermal method using thioacetamide as asource of sulfide ion, in addition to the uniformly formed nanoparticles, has highreproducibility which is a good criterion for increasing the scaling rate.
