Graphical abstract: - Highlights: • Cu{sub 2}S thin films with hierarchical nanostructures have been synthesized by solvothermal method using DMSO as reactant. • The band gap is estimated to be 1.0 eV of the Cu{sub 2}S hierarchical nanostructures. • The form process of Cu{sub 2}S and the possible mechanism of hierarchical nanostructures were proposed. - Abstract: In this paper, Cu{sub 2}S thin film with hierarchical petal-like nanostructures has been successfully in situ synthesized via a solvothermal method using DMSO as reactant under appropriate reaction conditions. The crystalline phase, morphology and optical properties of the resulting products were characterized by X-ray diffraction, energy-dispersive X-ray spectrometry, scanning electron microscopy and UV–vis absorption spectroscopy, respectively. The band gap is estimated to be about 1.0 eV by the results of UV–vis absorption spectroscopy of the Cu{sub 2}S thin film with hierarchical nanostructures that consisted of nanoslices with the thickness of 15 nm. The formation process of Cu{sub 2}S and the possible mechanism of hierarchical nanostructures were also proposed. These findings are valuable since Cu{sub 2}S thin film with hierarchical petal-like nanostructures are promising candidate as lithium ion battery and solar cell materials.
