Title:
LIGHT-EMITTING MATERIAL, OXYGEN SENSOR, AND COATING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/167278
Kind Code:
A1
Abstract:
The light-emitting material contains two or more types of rare earth element ions and a linker ligand that forms coordination bonds with 2-4 rare earth element ions, and the two or more types of rare earth element ions and linker ligand form a rare earth complex. The two or more types of rare earth element ions include at least one type of rare earth element ion selected from the group consisting of Yb, Nd, Sm, Eu, Tb, Dy, Ce, Pr, Ho, Er, and Tm and at least one type of rare earth element ion selected from the group consisting of Y, La, Gd, and Lu. The linker ligand has a linker group and a substituent containing a coordination-bonding functional group that forms a coordination bond with a rare earth element ion, bonded to the linker group, or has a linker group containing a coordination-bonding functional group that forms a coordination bond with a rare earth element ion.
