▎ 摘 要
NOVELTY - Nitrogen-containing graphene structure has single layer or multilayer graphene nanosheet, and nitrogen is introduced into the graphene structure. USE - Nitrogen-containing graphene structure is used for fluorescent substance dispersion liquid (claimed) used for probe for detecting biochemical reaction, light emitting diode, display and fluorescent tag. ADVANTAGE - The nitrogen-containing graphene structure has excellent hydrophilicity and luminous efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for fluorescent substance dispersion liquid, which is obtained by dispersing nitrogen-containing graphene structure into the solvent.
