A new way to synthesize ZnS nanoparticles

ZnS nanoparticles were prepared with normal ZnO and Na2S by solid–liquid chemical reaction under ultrasonic condition and characterized by XRD, TEM, SEM, IR and TG–DTG. The results showed that these particles were good crystal cubic zinc blended with average size of 50 nm, possess good IR transmittance in the range of 400–4000 cm and good thermal stability.
