Uniform Cu 2 MnSnS 4 nanosheets with an average size of 50 nm are synthesized through a mild solvothermal solution approach. The as‐prepared Cu 2 MnSnS 4 nanosheets have the wurtzite structure and are oriented parallel to the (002) crystal plane. The structure, morphology, composition, and optical absorption properties of the as‐prepared samples are characterized by X‐ray powder diffraction, transmission electron microscopy, energy dispersive X‐ray spectrometry, scanning electron microscopy, and UV/Vis spectrophotometry. The formation mechanism of the Cu 2 MnSnS 4 nanosheets is also discussed. A thin film prepared from the Cu 2 MnSnS 4 nanosheets displays a clear photoelectric response, suggesting its potential application as a low‐cost solar absorber material. The Cu 2 MnSnS 4 nanosheets are also found to show weak ferromagnetic behavior below 5 K.
