Abstract
Nanovectors technology is a comprehensive solution, which comprises unique luminescent nanolabels, dedicated equipment for reading of the same and verification algorithms – all devoted for anti-forgery protection of valuable objects. Nanovectors themselves have a complex and unique luminescence spectrum fingerprint resulting from the selection of their composition, type and substrates, which make any attempt to fake the spectral information practically impossible. Nanovectors constitute a special code enabling correct identification only for specified measurement conditions. Moreover, nanovectors may be used for marking of a wide range of products such as documents, ID cards, access cards and employee cards, spare parts, elements of packaging, liquids, greases etc. Either entire volume of objects during their production process, pressing in a specified location of an object after production or unique printing on the object’s surface may be conveniently employed. Nanovectors are most often manufactured as invisible security features and, therefore, special tools are necessary to detect their presence. This work was focused on experimental verification of reproducibility of Nanovectors reading and theoretical estimation of maximal number of distinguishable optical codes, which confirmed the ability to unequivocally design thousands of such spectral fingerprints.
