▎ 摘　　要

NOVELTY - A graphene nanosheet stacked body comprises graphene nanosheets which are included in matrix material, in which average interlayer distance of graphene nanosheets is 0.35-2 nm. USE - A graphene nanosheet stacked body for aggregate of graphene nanosheet stacked body used for wavelength conversion film and fluorescent probe (all claimed). ADVANTAGE - Luminous efficiency, durability, and heat resistance of wavelength conversion film or fluorescent probe containing the graphene nanosheet stacked body can be improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) aggregate of graphene nanosheet stacked body containing greater than or equal to 2 graphene nanosheet stacked bodies; (2) wavelength conversion film comprising base material and wavelength conversion layer containing aggregate of graphene nanosheet stacked body or graphene nanosheet stacked body; and (3) fluorescent probe containing aggregate of graphene nanosheet stacked body or graphene nanosheet stacked body.
