発明の名称 (英語) RARE EARTH COMPOUND, LIGHT-EMITTING BODY, LIGHT-EMITTING DEVICE, WAVELENGTH CONVERSION MATERIAL, AND SECURITY MATERIAL
発明の概要(英語) Disclosed is a rare earth compound which contains two trivalent rare earth ions and two phosphine oxide ligands represented by formula (I). The two rare earth ions are connected to one another by the two phosphine oxide ligands which are coordinated to both of the rare earth ions. X1 represents a halogen atom, a C1-20 hydrocarbon group, or the like.
従来技術、競合技術の概要(英語) BACKGROUND ART
The fluorescent material light-emitting diodes efficiently, the light emitting device, the wavelength converting material, such as security material is applied to a variety of applications have been expected. As the fluorescent material, inorganic fluorescent material (for example, Patent Document 1) of the other, using a strong light absorption by organic ligands and also the rare-earth compound has been proposed (for example, Patent Document 2 and Patent Document 3).
