▎ 摘　　要

NOVELTY - Complex comprises a graphene layer and a porphyrin layer formed on the graphene layer, where the porphyrin layer is doped with a metal. USE - Complex used in optical sensor (claimed). ADVANTAGE - The complex improves optical sensor characteristics including both organic and inorganic characteristics, and has high stability and sensitivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing complex, which involves forming porphyrin layer on graphene layer, and then doping the porphyrin layer with a metal to form the complex. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flowchart of the method for manufacturing graphene-based hybrid material.
