NITROGEN-CONTAINING GRAPHENE STRUCTURE AND PHOSPHOR DISPERSION LIQUID

摘要

PROBLEM TO BE SOLVED: To provide a novel nitrogen-containing graphene structure exhibiting relatively high light emitting efficiency, and to provide a phosphor dispersion liquid using the novel nitrogen-containing graphene structure.

SOLUTION: The nitrogen-containing graphene structure is configured from a single layer of graphene nanosheet or multiple layers of graphene nanosheets and includes: a sheet portion including an armchair-shaped edge surface at the edge of the sheet; a terminal six-membered ring which shares and bonds with only one side of the armchair-shaped edge surface; and a nitrogen-containing functional group which bonds to at least one carbon atom selected from among a carbon atom that does not bond to the armchair-shaped edge surface among the carbon atoms constituting the terminal six-membered ring, and a carbon atom constituting the sheet portion. The phosphor dispersion liquid is formed by dispersing such a nitrogen-containing graphene structure into a solvent.
