▎ 摘　　要

NOVELTY - Light-based quantum dot/graphene film photodetection material comprises base layer, response transmission dual function layer and enhanced response layer. The base layer material is a flexible material to transporting the bifunctional layer material is a material having a conductive and photoresponse and enhanced response layer material for the light response of the quantum dot material. USE - The material is useful for intelligent wearable device (claimed). ADVANTAGE - The method is simple. The material has high sensitivity, flexibility and high strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing light-based quantum dot/graphene film photodetection material, comprising (i) adding The oxidized graphite into deionized water at room temperature, stirring, carrying out ultrasonic dispersion to obtain a oxidized graphite dispersion, centrifuging, separating, taking supernatant, placing the flexible material in the sand core funnel on top of the microporous membrane, adding the supernatant into the sand core funnel, vacuum filtering, carrying out chemical reduction and obtaining graphene film based on a flexible material; and (ii) forming quantum dot material having a photoresponse on the surface of a graphene film based on a flexible material.
