NANOPARTICLE LUMINESCENT MATERIAL, ELECTROLUMINESCENT ELEMENT USING THE SAME, INK COMPOSITION AND DISPLAY APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain a nanoparticle luminescent material having a specific ligand and an electroluminescence element having a high-luminescence efficiency.

SOLUTION: The nanoparticle luminescent material 1 comprises a core part composed of a nanoparticle 13 and a shell part composed of at least two kinds of ligands localized on the surface of the core part. At least one kind of the ligands is a hole transporting ligand 12 and at least one kind is an electron transporting ligand 11.
