摘要
Herein, FePS3/reduced graphene oxide heterostructure has been prepared via a typical hydrothermal process, and flexible photodetectors based on hybrids have been subsequently fabricated. The photoresponse measurement results demonstrate that the photodetector exhibits obvious photoelectric conversion behavior without applied potential, indicating that the device possesses the capability to be self-powered. In addition, the photocurrent density of the as-fabricated photodetectors reaches up to 125 nA cm-2under 90 mW cm-2illumination intensity without an external power source, which is 5.86 times higher than single FePS3-based devices. Furthermore, the maximum attenuation in photocurrent density of the as-fabricated flexible photodetectors measured at -0.3 V after different bending cycles and bending angles is 29.8% and 17.7%, respectively. These results demonstrate that the as-fabricated photodetectors have excellent flexibility and provide a simple and effective strategy for the construction of flexible photodetectors.
