Abstract
The steady growth of the counterfeit market necessitates the development of protection systems for original products. Here we demonstrate a femtosecond laser-induced printing of all-dielectric silicon nanoparticles onto polypropylene substrate. The optical properties of res-onant silicon nanoparticles and its spatial distribution within an area are suitable for a forensic security feature authentication. So, the proposed fabrication method is promising for a modern design of security tag development.
