▎ 摘　　要

CdSxSe1-x-graphene composites were prepared by a solvothermal process using cadmium acetate as Cd precursors, sulfourea as S precursors and selenium powder as Se precursors. CdSxSe1-x-graphene composites were characterized by X-ray diffraction, scanning electron microscope and ultraviolet-visible absorption spectroscopy. The photoelectric properties of CdSxSe1-x-graphene and bare CdSxSe1-x were investigated by transient photocurrent responses and three-electrode cyclic voltammetry. Compared with bare CdSxSe1-x, CdSxSe1-x-graphene composites show the improved photoelectric characteristics in the presence of graphene. (C) 2015 Elsevier Ltd and Techna Group S.r.l.
