A simple synthesis route to CdS nanomaterials with different morphologies by sonochemical reduction

摘要

CdS nanocrystallines with different morphologies have been prepared by a sonochemical synthesis at room temperature using hydroxyethyl cellulose (HEC) as embedding material and soft templates. The obtained CdS samples can exhibit spherical, rod and dendritic morphologies by adjusting the concentration of the starting materials. The possible growth mechanism for different morphologies of CdS semiconductors was discussed. This approach may also apply to prepare other metal sulfide nanomaterials with different shapes.
