Title (EN) MULTI-FUNCTIONAL MATERIAL COMPOSITIONS, STRUCTURES INCORPORATING THE SAME AND METHODS FOR DETECTING AGEING IN LUMINESCENT MATERIAL COMPOSITIONS
(FR) COMPOSITIONS À BASE DE MATÉRIAUX MULTIFONCTIONNELS, STRUCTURES LES INCORPORANT ET PROCÉDÉS DE DÉTECTION DU VIEILLISSEMENT DANS DES COMPOSITIONS À BASE DE MATÉRIAUX LUMINESCENTS
Abstract: front page image
(EN)A multi-functional material composition comprising a zirconia host and containing a luminescent lanthanide oxide additive, in particular dysprosia (Dy2O3), wherein the lanthanide oxide additive is effective both in stabilizing the zirconia and providing for luminescent temperature sensing, and a method of determining a remaining useful life- time for the luminescent material composition from the proportion of a monoclinic phase (m) in the material composition.
(FR)La présente invention concerne une composition à base de matériaux multifonctionnels comprenant un hôte en zirconium et contenant un additif oxyde de lanthanide luminescent, en particulier la dysprosie (Dy2O3), l'additif oxyde de lanthanide étant efficace à la fois pour stabiliser le zirconium et détecter la température par luminescence. L'invention concerne également un procédé de détermination d'une durée de vie utile restante pour la composition à base de matériaux luminescents à partir de la proportion d'une phase monoclinique (m) dans la composition de matériaux.
