ORGANIC-INORGANIC COMPLEX CONTAINING LIGHT EMITTING RARE-EARTH METAL NANO CLUSTER AND ANTENNA LIGAND, AND MANUFACTURING METHOD OF LIGHT-EMITTING ARTICLE AND LIGHT-EMITTING COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a fluorescent material which absorbs light or different wavelengths, and then emits the light again.;SOLUTION: There is provided a composition containing an organic polymer matrix, rare-earth metal nano clusters dispersed in the polymer and an antenna ligand arranged outside the rare-earth metal nano clusters, in which the rare-earth metal nano clusters are within a size range of 1 to 100 nm, and the composition contains lanthanide atoms bonded to at least one semimetal or transition metal via an oxygen atom or a sulfur atom.;COPYRIGHT: (C)2014,JPO&INPIT
