In this study, plasmonic Au nanostructures in soda-lime-silicate float glasses have been generated by gold coating and ArF-excimer laser irradiation (193 nm) of the glass surface. The formation of Au nanoparticles could be verified by the surface plasmon resonances between 530 and 600 nm, which were obtained by optical spectroscopy. Furthermore, the implantation of these nanoparticles into the glass as a consequence of melting of the glass surface by the laser has been investigated by means of electron microscopy (SEM and TEM). Here the absorption of the glass at the laser wavelength plays an important role. The implantation of the nanoparticles into the glass is an important condition to generate corrosion resistant laser marks, for example micro patterns, which are of specific interest for applications of nanoplasmonics, nanoantennas and labeling by holograms.
