Abstract

Das hier beschriebene Verfahren betrifft eine neue Methode zur optischen Markierung von Produkten sowie Marker, mit deren Hilfe dieses Verfahren durchführbar ist. Die zu authentizierenden Produkte werden mit einem oder mehreren fluoreszierenden oder phosphoreszierenden Farbstoffen markiert, deren Abklingzeit der Fluoreszenz oder Phosphoreszenz gemessen und als Information für eine Identifikation bzw. Authentikation eines Produktes verwendet wird. Die Abklingzeiten der Farbstoffe werden auf zweierlei Weise moduliert, nämlich entweder durch Variation der chemischen Struktur oder durch Zusatz einer zweiten Substanz, die die Abklingzeit des Fluorophors oder Phosphors messbar und reproduzierbar verändert. Produkte, die mit Markierungsstreifen oder Punkten versehen sind, die derartige Farbstoffe oder Farbstoffkombinationen enthalten, können über die Messung der Abklingzeit eindeutig authentiziert, codiert oder zugeordnet werden. Die erfindungsgemäßen Fluoreszenzfarbstoffe besitzen eine Abklingzeit von mindestens 0,1 ns, die Phosphoreszenzfarbstoffe eine Abklingzeit von mehr als 100 ns. Die Phosphoreszenzfarbstoffe sind somit auch zeitaufgelösten Messverfahren zugänglich.The method described here relates to a new method for the optical marking of products and markers, with the help of this method is feasible. The products to be authenticated are labeled with one or more fluorescent or phosphorescent dyes whose fluorescence or phosphorescence decay time is measured and used as information for identification or authentication of a product. The cooldowns of the dyes are modulated in two ways, either by varying the chemical structure or by adding a second substance that measurably and reproducibly alters the cooldown of the fluorophore or phosphorus. Products provided with marker strips or dots containing such dyes or dye combinations can be uniquely authenticated, coded or assigned by measuring the cooldown. The fluorescent dyes according to the invention have a cooldown of at least 0.1 ns, the phosphorescent dyes have a cooldown of more than 100 ns. The phosphorescent dyes are therefore also accessible to time-resolved measurement methods.
