Mechanochemical route for sulphide nanoparticles preparation

摘要

Well-crystallized ZnS, CdS and PbS nanoparticles were successfully synthesized by the mechanochemical route from the corresponding acetates and Na_2S. X-ray powder diffraction and scanning electron microscopy were used to characterize the as-obtained products. The SEM measurements show the aggregates of small nanocrystals in which particle sizes of 5-18nm were estimated by Scherrer's formula. Simple flow chart of the preparation of sulphide nanoparticles was presented.
