  A novel and simple solid-liquid chemical reaction route is proposed to synthesize ZnS nanoparticles.In the method, ZnS nanoparticles were prepared by reaction of ZnO and Na2S in water with ultrasonic radiation at low temperature.The effects of process parameters on the properties of ZnS particles were investigated.The products were characterized by X-ray diffraction (XRD), scan electron microscope (SEM), transmission electron microscopy (TEM), infrared spectroscopy (IR), thermogravimetry-differential thermogravimetry (TG-DTG), and fluorescence emission spectroscopy.The results show that these particles are good crystalline zinc blende with average size of 35 nm, possess good IR transmittance in the range of 400 to 4000 cm-1 and good thermal stability in oxygen.
