▎ 摘　　要

CsPbBr3/Reduced Graphene Oxide (RGO) nanocomposites were prepared by a facile hot-injection method. The crystalline structure and morphologies of the as-synthesized CsPbBr3/RGO nanocomposites were characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The photoluminescence (PL) spectra indicated that CsPbBr3/RGO nanocomposites displayed strong quenching phenomenon compared with the pure CsPbBr3 as the probably reason of the fast separation and transfer of the photogenerated hole-electron pair. Moreover, the PL decay results of the CsPbBr3/RGO nanocomposites (tau(ave)= 4.52ns) was relatively shorter than that of the corresponding CsPbBr3 nanoparticles (tau(ave) =14.72 ns), demonstrated the charge transfer between the CsPbBr3 nanoparticles and graphene. Meanwhile, an enhanced strong photoresponse was demonstrated by the CsPbBr3/RGO nanocomposites, which showed tremendous potential applications in the field of photoelectric detection.
