摘要：
The present invention provides a fluorescent substance excellent in emission intensity and in emission efficiency. The substance can be excited by light at a longer wavelength than ever. The present invention also provides a luminous composition comprising the fluorescent substance and a light-emitting element using the substance. The fluorescent substance comprises a rare earth metal and a phosphine oxide ligand which coordinates to said rare earth metal and said ligand containing at least one siloxane bond in its structure. The fluorescent substance can be produced from a reaction between a compound having a siloxane bond and a rare earth complex coordinated by a phosphine oxide ligand. The luminous composition comprises the fluorescent substance.
