▎ 摘　　要

Low-dimensional carbon materials, such as conducting graphene, semiconducting C-60 and their hybrids, have recently received a great deal of attention for the potential applications in low-cost flexible and wearable nanoelectronics, due to their remarkable mechanical, electrical and optoelectronic properties. While graphene exhibits intrinsically weak absorption and C-60 is typically associated with low carrier mobility and short exciton diffusion length, the marriage of two materials is a synergetic route to overcome these technical short-comings. Here, we fabricate a van der Waals bonded graphene/C-60 hybrid on a plastic substrate to demonstrate a highly sensitive flexible photodetector. Intimate electronic coupling across the all-carbon interface allows highly efficient interfacial charge transfer, which effectively dissociates the electron-hole pairs and leads to significant photoresponse across ultraviolet to near-infrared (similar to 10(4) A/W @ 405 nm). Thanks to remarkable absorption of C-60, it enables the detection of weak signals including those from a lighter and fluorescent lighting. Simultaneously, the photodetector exhibits extraordinary mechanical flexibility, allowing excellent electric conductivity and stable light detection under quite large tensile strain. Furthermore, the flexible devices still exhibit a satisfactory photoresponse after 6 months, indicating the excellent environmental robustness. This scalable all-caron hybrids may provide a viable route to produce the high-performance flexible optoelectronic devices. (C) 2020 Elsevier Ltd. All rights reserved.
