The generation of plasmonic Au/Ag nanostructures in glass surfaces showing a tunable surface plasmon resonance in a wide range of wavelengths should be realized by laser implantation of gold by means of excimer laser irradiation. These are promising materials for optoelectronics and nanoplasmonics. Thin films of Au were applied to the glass surface and then Au species were incorporated by means of intense UV radiation using fluences below the ablation threshold of the glass. The formation of Au and Au/Ag nanoparticles with surface plasmon resonances between 500 and 620 nm could be verified by optical spectroscopy. These results demonstrate that such procedures enables the space-selected generation of plasmonic Au/Ag structures in glass surfaces by excimer laser irradiation.
