Abstract:
1. A nitrogen-containing graphene structure, comprising: a graphene structure having a sheet portion comprised of a monolayer or multilayer graphene nanosheet; and nitrogen introduced into the graphene structure, wherein: the sheet portion comprises, at an edge portion thereof, an armchair edge-face portion and a terminal six-membered ring bound to the armchair edge-face portion while sharing only one side therewith, the nitrogen comprises nitrogen introduced into the graphene structure in the form of one or more amino groups and amide groups bound to one or more carbon atoms selected from: the nitrogen-containing graphene structure has an average mass of 1000 m/z to 50000 m/z, the nitrogen-containing graphene structure has a nitrogen content of 5 wt % to 50 wt %, and the nitrogen-containing graphene structure emits light and has an emission efficiency of 15% or greater.
