(FR) NANOTUBES LUMINESCENTS À BASE D'ALUMINATE DE BÉRYLLIUM, DE MAGNÉSIUM, DE CALCIUM, DE STRONTIUM OU DE BARYUM DOPÉS AVEC DU CÉRIUM (III) ET CO-DOPÉS AVEC D'AUTRES IONS DE LANTHANIDES M(1-X-Y)N2O4: CEX, LNY
Abstract: front page image
(EN)The present invention provides luminescent aluminate nanotubes doped with rare-earths, namely from the Lanthanide Series of Elements (Ln is La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, Tm and Lu), formula of which proves to be M(1-x-y) N2O4:Cex, Lny, where M comprises an alkaline-earth-metal cation consisting of Be, Mg, Ca, Sr, Ba or mixtures thereof, N is Al, accepting the co- doping by a combination of lanthanide ions (co) activators of luminescence, where Q
(FR)Cette invention concerne des nanotubes luminescents à base d'aluminate dopés avec des terres rares, c'est-à-dire provenant de la série des lanthanides (Ln est La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, Tm et Lu), dont la formule s'avère être M(1-x-y) N2O4:Cex, Lny. Dans la formule, M comprend un cation de métal alcalino-terreux constitué par Be, Mg, Ca, Sr, Ba ou des mélanges de ceux-ci, et N est Al. Lesdits nanotubes luminescents acceptent également le co-dopage avec une combinaison de (co)-activateurs de luminescence du type ions de lanthanides, où Q
