چکیده:

Results of the synthesis of ZnS nanoparticles (NPs) in aqueous dispersion from ZnSO4 and Zn(CH3COO)2, heated by means of microwaves are presented in this paper. A 1650 W oven operating at (60 and 100% of the nominal power in periods of (60 seconds was employed. The obtained dispersions where analyzed by UVvis, X-rays diffraction, photoluminescence and transmission electron microscopy. At100% of applied power the obtained ZnS, NPs average size is 30nm. It was estimated that concentration of NPs is affected by the applied power during synthesis, while electromagnetic properties are affected by the employed precursors.
