We demonstrate that such nanoarrays are plasmon active. Raman spectroscopy was applied to study molecular probe 4-aminothiophenol (4-ABT) absorbed onto a silver nanostructured array. The observed Raman spectra show peaks arising from b2 modes, which occur for plasmon enhanced Raman from 4-ABT in place of a1 modes, which occur in normal Raman scattering. We demonstrate that the PPLN and PPE substrates possess different plasmonic properties with PPE creating a stronger SERS signal relative to PPLN substrates.||Type of material:||Journal Article||Publisher:||ACS Publications||Copyright (published version):||2012 American Chemical Society||Keywords:||Ferroelectric lithography;SERS;Periodically poled lithium niobate;Periodically proton exchanged||DOI:||10.1021/jp310248w||Language:||en||Status of Item:||Peer reviewed|
