Abstract

In₂S₃ nanoparticles, short nanowhiskers, nanorods and finger-structure nanocrystals with stoichimetric composition and high quality can be prepared by a solvent-reduction route. It was found that the reagent concentrations, solvent and reaction temperature played important roles in the shape control. We also successfully used CTAB to modify the shape of products. The resulting structures were found to be quantum-confined.
