Title (EN) MULTIPLE RARE-EARTH METAL COMPLEXES
(FR) COMPLEXES MULTIPLES DU GROUPE DES TERRES RARES
Abstract:
(EN) The invention pertains to a rare-earth metal ion complex, characterized in that the complex comprises at least two complexing moieties, each of which is complexed with a rare-earth metal ion. Preferably, the rare-earth metal ion is selected from Yb3+ (ytterbium(III) ion), Er3+ (erbium(III) ion), Tb3+ (terbium(III) ion), Tm3+ (thulium(III) ion), Ho3+ (holmium(III) ion), Eu3+ (europium(III) ion), and Nd3+ (neodymium(III) ion). Preferred is the rare-earth metal ion complex which further comprises at least one sensitizer, preferably an organic sensitizer. The rare-earth metal ion complex can be used in optical devices and diagnostic kits.
(FR) L'invention concerne un complexe d'ions métalliques du groupe des terres rares. Ce complexe se caractérise en ce qu'il comprend, au moins, deux fractions complexantes, chacune étant complexée avec un ion métallique des terres rares. De préférence, cet ion métallique des terres rares est sélectionné parmi Yb3+ ion ytterbium (III), Er3+ (ion erbium (III)), Tb3+ (ion terbium (III), Tm3+ (ion thulium (III), Ho3+ (ion (holmium (III), Eu3+ (ion europium (III) et Nd3+ (ion néodymium (III). De préférence, le complexe d'ion métallique des terres rares comprend, en outre, au moins un sensibilisateur, et de préférence, un sensibilisateur organique. Le complexe d'ions métallique des terres rares peut être utilisé dans les dispositifs optiques et les kits de diagnostique.
