Graphene with excellent mechanical properties shows potential applications in flexible devices. By decorating graphene with ZnO nanoparticles, the response of graphene-based flexible light sensor to light was enhanced. The light sensor showed different response rates with light intensities under different wavelength which indicated that the as-designed sensor can be used to detect the wavelength and intensity of light simultaneously. The microstructures and photonic properties of the hybrid device revealed that the interface played an important role on the performance of device. This result confirmed the method to prepare graphene/ZnO hybrid light sensor are convenient and economical, which may be applied in wearable devices.
