We studied such gold nano-triangle arrays on silicon or glass substrates. A series of different samples was investigated with a parabolic mirror based confocal microscope where the sample is scanned through the laser focus. By employing higher order laser modes (azimuthally and radially polarised laser beams), we can excite the Fischer patterns using either a pure in-plane (x,y) electric field or a strongly z-directional (optical axis of the optical microscope) electric field. We collected and evaluated the emitted luminescence and thereby investigated the respectively excited plasmonic modes. These varied considerably: firstly with the light polarisation in the focus, secondly with the aspect ratio of the triangles and thirdly with the employed substrate. Moreover, we obtained strongly enhanced Raman spectra of an adenine (sub-)monolayer on gold Fischer patterns on glass. We thus showed that gold Fischer patterns are promising surface-enhanced Raman scattering (SERS) substrates.</dcterms:abstract> <dspace:isPartOfCollection rdf:resource=""/> <dc:creator>Kolloch, Andreas</dc:creator> <dc:creator>Meixner, Alfred J.</dc:creator> <dc:contributor>Hennemann, Laura E.</dc:contributor> <dcterms:available rdf:datatype="">2013-02-21T11:24:49Z</dcterms:available> <dc:contributor>Zhang, Dai</dc:contributor> <dc:contributor>Kern, Andreas</dc:contributor> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:contributor>Kolloch, Andreas</dc:contributor> <dcterms:isPartOf rdf:resource=""/> <dc:contributor>Boneberg, Johannes</dc:contributor> <dc:creator>Hennemann, Laura E.</dc:creator> <dc:language>eng</dc:language> <dc:rights>terms-of-use</dc:rights> <dcterms:bibliographicCitation>Beilstein journal of nanotechnology ; (2012), 3. - S. 674-683</dcterms:bibliographicCitation> </rdf:Description> </rdf:RDF>
