Copper sulfides, such as Cu 7 S 4 , Cu 1.8 S, Cu 1.81 S and Cu 2 S, in the wire‐like, and solid and hollow ball‐like shapes congregated from nano‐spherical particles and nanoslices, have been prepared by a solvothermal method using a mixture of water and ethylene glycol as solvent. CuSO 4 and thiourea were used as the starting materials without assistance of any surfactant or template. The results show that the water content in the solvent affects the morphology of the samples, and the reaction time and temperature affect the crystal structure and morphology. On the basis of the obtained results, the formation processes of different morphologies of copper sulfides can be interpreted by the following mechanism: nanoparticles of copper sulfides initially formed, then the wire‐like structures were gradually created, and finally translated to solid and hollow spherical structures under the different experimental conditions.
