Abstract (EN): To evaluate the effectiveness of Raman microspectroscopy in euro banknotes' recognition, several genuine and fake 10 and 20 euro banknotes were analyzed. Raman microspectroscopy revealed itself to be very useful in the detection of differences in the inks used to provide the color on the banknotes. However, the study revealed that the Raman analysis results are not decisive to guarantee the authenticity of a specific banknote since similar Raman spectra were obtained for genuine and fake banknotes. Even the Raman microspectroscopy analysis obtained for the same color on different areas of fake banknotes revealed similar spectra, and this can help law enforcement agencies to identify counterfeit tracking routes.
