Generation And Characterization Of Plasmonic Nanostructures In Glass Surfaces By Means Of Excimer And Solid State Laser Irradiation

The generation of metal nanoparticles and appropriate arrays thereof in surface regions of silicate glasses was realized by means of ultraviolet laser irradiation (193 nm and 405 nm). Especially, the excimer laser irradiation of 193 nm allowed the formation of nanoscaled structures at high resolution. The precipitation of neutral metal atoms (Ag, Au) and the growth of nanostructures occur due to laser irradiation without any subsequent thermal treatments. The interesting surface plasmon resonances were registered in UV/Vis range as a function of sizes and origin of nanoparticles and of specific arrays like line grating configurations.
