Title:
NITROGEN-CONTAINING GRAPHENE STRUCTURE, AND PHOSPHOR DISPERSION LIQUID
Document Type and Number:
WIPO Patent Application WO/2012/086260
Kind Code:
A1
Abstract:
A nitrogen-containing graphene structure is provided with: a graphene structure configured from one graphene nanosheet or multiple layers of graphene nanosheets; and nitrogen introduced into the graphene structure. Preferably, the nitrogen-containing graphene structure is provided with a graphene structure configured from one graphene nanosheet or multiple layers of graphene nanosheets and having: a sheet portion including an armchair-shaped edge surface at the edge of the sheet; and a terminal six-membered ring which shares and bonds with only one side of the armchair-shaped edge surface. Preferably, the nitrogen-containing graphene structure is also provided with a nitrogen-containing functional group which bonds to at least one carbon atom selected from among a carbon atom (a) that does not bond to the armchair-shaped edge surface among the carbon atoms constituting the terminal six-membered ring, and a carbon atom (b) constituting the sheet portion (including the carbon atoms on the sheet portion sharing a side with the terminal six-membered ring). A phosphor dispersion liquid is formed by dispersing such a nitrogen-containing graphene structure into a solvent.
