(FR) ÉLÉMENTS DE SÉCURITÉ LISIBLES PAR MACHINE ET PRODUITS LES CONTENANT
Abstract: front page image
(EN)This invention relates to a machine readable luminescent security element and an apparatus and method for checking the luminescent security element. The invention is characterised in that security element contains at least two pigments, the first pigment comprising a first inorganic host lattice doped with a first dopant, that is a first luminescent ion, the second pigment comprising a second inorganic host lattice doped with at least two dopants, the said first dopant and a luminescent rare earth ion to which energy may be transferred non-radiatively from the first dopant in the second inorganic host lattice and which largely quenches the emission from the first dopant in the second inorganic host lattice at one or more emission peaks.
(FR)L'invention concerne un élément de sécurité luminescent lisible par machine ainsi qu'un appareil et un procédé de vérification de l'élément de sécurité luminescent. Cette invention est caractérisée en ce que l'élément de sécurité contient au moins deux pigments, le premier comprenant un premier réseau hôte minéral dopé avec un premier dopant, qui est un premier ion luminescent, le second pigment comprend un second réseau hôte minéral avec au moins deux dopants, le premier dopant et un ion du groupe des terres rares luminescent auquel une énergie peut être transférée de manière non radioactive du premier dopant vers le second réseau hôte minéral et qui désactive l'émission du premier dopant vers le second réseau hôte minéral à un ou plusieurs pics d'émission.
