Title: (FR) PARTICULES LUMINESCENTES A BASE DE TERRES RARES ET LEUR UTILISATION A TITRE D'AGENT DE DIAGNOSTIC
Abstract: front page image
(FR) La présente invention concerne une particule luminescente comprenant une nanoparticule de formule A1-xLnxVO4(1-y)(PO4)y (I) dans laquelle A est choisi parmi l'yttrium (Y), le gadolinium (Gd), le lanthane (La) et leurs mélanges ; Ln est choisi parmi l'europium (Eu), le dysprosium (Dy), le samarium (Sm), le néodyme (Nd), l'erbium (Er), l'ytterbium (Yb) et leurs mélanges ; 0 < x < 1; et 0 < y < 1 ; caractérisée en ce que la nanoparticule présente en surface des cations tétraalkyl ammonium. Elle concerne également un procédé de préparation de telles particules luminescentes, une suspension colloïdale de ces particules, et leur mise en œuvre à titre d'agent de diagnostic, ainsi qu'un kit de diagnostic comprenant de telles particules luminescentes.
