Copper sulfide (CuS) submicrometer hollow structures have been synthesized by γ-irradiating in an aqueous SDS-Na,2,S,2,O,3, solution containing CuCl,2, at room temperature and under ambient pressure. The obtained CuS hollow structures were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM). The results indicate that the external diameter and inside diameter of the CuS hollow spheres are about 600 nm and 400 nm 20s, respectively. The shell thickness of the spheres is about 100 nm. It has been investigated that the radiation dose rate and surfactant can effect on the morphology of CuS and the possible formation mechanism of CuS hollow structure has also been discussed.
