Authentication of Czech Banknotes using Raman Microscopy

Popis výsledku v původním jazyce

At the present time, all modern banknotes contain security features to prevent their counterfeiting. Some of these features include special paper and inks with a specific composition as well as tints that are hard to reproduce by commercial copiers and printers. Current availability of digital technologies makes it much easier to produce higher quality counterfeits than in the past. This paper is focused on systematical experimental examination of paper and inks used on Czech banknotes to obtain characteristic Raman spectra that serve for the authenticity assessment. Raman spectroscopy is a powerful method for material identification and meets requirements of the forensic examination. This method has the potential to recognize various substances, even their structural modification. On the basis of Raman spectra, it is possible to determine whether the questioned banknote is genuine or a forgery, even though the specific composition of inks is a manufacturing secret. Raman spectral data of the investigated Czech banknotes were used for creation of a spectral library for the purpose of further verification of questionable banknotes.
