Femtosecond laser writing of metallic nanostructures using silver photo-reduction

摘要

We report on fabrication of silver nanostructures using femtosecond laser lithography in silver-containing polymers.Various metallic structures were fabricated using tightly focused femtosecond laser beam having circular and linearpolarization. Fine gratings consisting of ripple patterns were fabricated using linear polarization, and nanorings havingsize below the diffraction limit were fabricated using circular polarization. This approach offers a promising route forrealization of plasmonic nanostructures on flexible substrates.
