Remote-excitation surface-enhanced Raman scattering using propagating Ag nanowire plasmons.
نویسندگان
چکیده
Using propagating plasmons on silver nanowires as an excitation source we perform surface-enhanced Raman scattering (SERS) at a nanoparticle/wire junction located remotely from the laser illumination spot with sensitivities in a few molecules range. Simultaneous multisite remote-excitation SERS sensing can also be achieved.

Localized and propagating surface plasmon co-enhanced Raman spectroscopy based on evanescent field excitation.
The localized and propagating surface plasmon co-enhanced Raman scattering of 4-mercaptopyridine was observed based on evanescent field excitation. The most effective coupling of the localized and propagating surface plasmons resulted in a >50 times enhanced signal relative to signals obtained on vacuum-deposited silver film.
متن کاملHighly Efficient Surface Enhanced Raman Scattering (SERS) Nanowire/Ag Composites
Introduction: Optically based sensing provides advantages over electronic sensing because optical spectra can uniquely fingerprint a chemical compound, significantly reducing false alarms and simplifying the detection process. In addition, light can easily be directed over long distances, enabling remote sensing. One of the most promising optical sensing techniques is surface enhanced Raman sca...
متن کاملPlasmonic band gap structures for surface-enhanced Raman scattering.
Surface-enhanced Raman Scattering (SERS) of rhodamine 6G (R6G) adsorbed on biharmonic metallic grating structures was studied. Biharmonic metallic gratings include two different grating components, one acting as a coupler to excite surface plasmon polaritons (SPP), and the other forming a plasmonic band gap for the propagating SPPs. In the vicinity of the band edges, localized surface plasmons ...

The active substrates in surface enhanced Raman scattering (SERS) spectroscopy were prepared through self-assembly of nanoparticles on functionalized glasses. Colloidal silver nanoparticles (Ag NPs) were prepared chemically in two different sizes by reduction of AgNO3 using trisodium citrate and sodium borohydride. Gold–silver core–shell nanoparticles were also prepared to compare between the o...
متن کاملPolarization dependence of surface-enhanced Raman scattering in gold nanoparticle-nanowire systems.
We study the polarization dependence of surface-enhanced Raman scattering (SERS) in coupled gold nanoparticle-nanowire systems. The coupling between the continuous nanowire plasmons and the localized nanoparticle plasmons results in significant field enhancements and SERS enhancements comparable to those found in nanoparticle dimer junctions. The SERS intensity is maximal when the incident ligh...
