N2 - The main purpose of this study is to present a simplified and short process for the growth of zinc sulfide (ZnS) nanoparticles from five strategic precursors: zinc acetate, polyethyleneimine, thioacetamide, thiourea and rongalite. The first characterization is UVvis spectrum, the next is the Tauc model to calculate the direct energy bandgap which was 3.84 eV, subsequently TEM micrographs are presented. With this technique, hexagonal crystallographic planes can be observed, fitting the PDF#83-2377 pattern. Furthermore, some particles with diameters between 25 and 29 nm which support the nanostructured nature of the compound, were found. In addition, zinc sulfide nanoparticles in suspension upon glass plane substrates were deposited through drop coating in order to observe nanoparticle agglomerations with the AFM technique. Finally, Raman dispersion and FTIR were measured and correlated.
