Copper sulfide(CuS)submicrometer hollow structures have been synthesized by γ-irradiating in an aqueous SDS-Na_2S_2O_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 microscow(TEM).The results indicate that the external diameter and inside diameter of the CuS hollow spheres are about 600 nm and 400 nln 20s.respectively.The shell thickness ofthe 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.
