Abstract: A novel homogenous precipitation method was developed for the preparation of monodisperse ZnS and CdS ultrafine particles, and the effects of solvent thermal treatment on the structures and morphologies of ZnS and CdS particles were investigated. The results show that the particles character as the growth of anion coordination tetrahedron during solvent thermal treatment, where blende-type ZnS particle is in the shape of double cone or tetrahedron, blend-type CdS appears as the tetrahedron, but wurtzite-type CdS is in the shape of cone. In addition, the particles with the better crystallinity are obtained with the increase of solvent thermal treatment temperature and time. This technology has such advantages as moving water and impurities, protecting CdS from oxidation and easily recycling organic reagent and so on.
