Synthesis and growth mechanism of hollow microcorn-like CdS crystal

Abstract

Hollow microcorn-like CdS crystals have been synthesized by a facile solvothermal method. The effects of molar ratio of Cd to S, pH value, and reaction time on the morphologies of CdS crystals were investigated by scanning electron microscopy (SEM). The results of transmission electron microscopy (TEM) and selective-area electron diffraction (SAED) show that the CdS crystals had predominately grown along the [001] direction. A possible growth process in the morphology of the hollow microcorn-like CdS crystals has been suggested.
