Title RARE EARTH COMPLEX, LUMINESCENT MATERIAL AND METHOD FOR PRODUCING SAME, AND LUMINESCENT SHEET AND METHOD FOR PRODUCING SAME
Abstract The rare earth complex according to the present invention has a rare earth atom, an organic ligand coordinated to the rare earth atom, and a polyoxometalate that contains a metal atom and an oxygen atom and that is coordinated to the rare earth atom.
Outline of related art and contending technology BACKGROUND ART
The rare-earth metal, amplified in, since it has the characteristic physical properties such as light, laser, display, illumination and the like are used in various devices.
Using the luminescent compound of the rare earth metal as, since the rare earth complex known. Having good light emission is a method for obtaining the rare earth complex, the emission center of the rare earth atoms to create many of the photoexcited state, prevent the deactivation of the molecular environment and vibration to create alternative methods. For example, Patent Document 1 is, effectively creating a state in which the photo excitation of the rare earth atoms to the organic ligand can be used, utilizing the fact that the photosensitizer disclosed since the rare earth complex. On the other hand, the non-patent document 1, in order to obtain a strong and advantageous as a molecule having the molecular structure of the vibration, and inorganic ligands coordinated to a rare earth complex is disclosed.
