Wurtzite-structured ZnS nanostructures have been synthesized by means of a microwave-solvothermal method
at 140°C using three precursors (chloride, nitrate and acetate). Different techniques such as X-ray diffraction (XRD), field
emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FT-IR) spectroscopy, ultraviolet–visible
(UV–vis) absorption spectroscopy and photoluminescence (PL) measurements have been employed to characterize this
material. The structure, surface morphology, chemical composition and optical properties were investigated as function of
precursor. In order to complement experimental results, first principles calculations at DFT level were carried out in order
to obtain the relative stability of the proposed intermediates along the formation mechanism.
Keywords: ZnS, Microwave-solvothermal method, precursors, first principle calculations.
