Abstract:
Nanostructured ZnS powders were prepared by solvothermal synthesis using zinc acetate and thiourea as precursors and PG, SDS and triton x100 as additive also using Taguchi experimental design. Four factors such as water to ethanol ratio (W/Et), type of additive, additive concentration and temperature were considered as the most effective parameters of the preparation route. The crystallite size was optimized as response of the experiments. Optimum condition for production of smaller crystals was determind as using a W/Et equals 1, PG as type of additive, 10mM as additive concentration and 120℃ as temperature. The structural and morphological properties of the producs were characterized using, field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD). FESEM micrographs showed agglomeration of spherical nanoparticles with an average particle size between 20 to 80 nm. XRD analysis revealed the cubic structure ZnS with high crystallinity in the range of 3.40 to 5.92 nm.
