Excimer laser irradiation allows the generation of high-resolution patterns of nanoparticles immediately below the glass surface, which are of specific interest for applications of nanoplasmonics (waveguides, nanowires, sensors, diffraction elements, SERS). Mono- and bimetallic Au/Ag nanoparticles could be used to create a tunable surface plasmon resonance (SPR) from 410 to 600 nm. Here, mono- and bimetallic Au/Ag nanoparticles were generated by irradiating silver ion containing and gold coated glass samples at laser fluences below the ablation threshold of the glass.
