| 20080303426 | FLUORESCENT RARE EARTH COMPLEX, AND LIGHT-EMITTING ELEMENT, SECURITY MEDIUM AND LIGHTING DEVICE USING THE SAME - The present invention provides a fluorescent rare earth complex having high solubility to a medium, showing fluorescence of high intensity and possessing excellent durability, and also provides a light-emitting element using that complex. The rare earth complex comprises a rare earth ion and a phosphine oxide ligand, and the phosphine oxide ligand contains a phosphorus atom connecting to at least one phenyl group. In the phenyl group, at least one of the meta-positions is substituted. It is also necessary that the para-position of the phenyl group be not substituted. | 12-11-2008 |
| 20090050851 | FLUORESCENT SUBSTANCE CONTAINING RARE EARTH METAL, LUMINOUS COMPOSITION COMPRISING THE SAME, PROCESS FOR MANUFACTURING THEREOF, AND LIGHT-EMITTING ELEMENT COMPRISING THE FLUORESCENT SUBSTANCE - 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. | 02-26-2009 |
