Abstract

L'objet de l' invention est un procédé pour vérifier si un substrat solide appelé "substrat à authentifier" est revêtu d' un vernis à base d'alkoxysiloxanes comprenant au moins un composé photoluminescent donné, sous la forme de nanoparticules, ledit procédé comprenant les étapes séquentielles : a) on expose ledit substrat à authentifier à un rayonnement excitateur; b) on acquiert son spectre de luminescence, c) on révèle une signature optique par comparaison du spectre de luminescence du substrat à authentifier avec celui obtenu à partir d' un substrat revêtu du vernis à base d' alkoxysiloxanes comprenant le au moins un composé photoluminescent donné, sous la forme de nanoparticules, appelé substrat de référence. L' invention concerne aussi l' utilisation de ce procédé pour l' authentification et/ou la détection de la contrefaçon d' objets tels que des verres optiques.
