LIGHT-EMITTING MATERIAL, LIGHT-EMITTING INK, LIGHT-EMITTING BODY, AND LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/009930
Kind Code:
A1
Abstract:
Disclosed is a light-emitting material including: a substrate that includes a metal oxide and/or a metal sulfide; two or more linker groups bonded to the substrate; a phosphine oxide ligand bonded to each of the linker groups, each phosphine oxide ligand having a single phosphine oxide group; and a rare earth ion. A rare earth complex is formed by a single rare earth ion and two or more phosphine oxide ligands.
