Abstract

La présente invention porte sur l'utilisation de nano-composés tels que des marqueurs de sécurité non désactivables comprenant un complexe de transfert de charge composé d'au moins deux agrégats atomiques quantiques (aqc) métalliques de taille différente. Ces nano-composés sont luminescents, en particulier fluorescents après excitation externe. L'invention porte également sur des documents, articles ou éléments de sécurité incorporant ces marqueurs, ainsi que sur un procédé et un système pour les détecter.
