The preparation and optoelectronic response of flexible composites via non-covalent coupling of quantum dots to chemically converted graphene is presented. The photoincluced charge transfer is confirmed by photoconductivity measurements and the photosensitivity is improved with increasing loadings of quantum dots. This opens up a new effective route to form composites for future large-area flexible and transparent optoelectronic devices.
