A novel in situ oxidization–sulfidation growth route via a self-purification process has been developed to synthesize β-In2S3 dendrites. To our best knowledge, this is the first example to prepare dendrites of III–VI compounds, which are expected to show particular physical properties. The X-ray analysis (EDXA), X-ray photoelectron spectra (XPS), Raman spectrum and optical properties of β-In2S3 dendrites have also been investigated. It is found that the product is pure In2S3 and shows the strong quantum confinement of the excitonic transition expected for the In2S3 dendrites.
