Plasmonics for Enhanced Vibrational Signatures
Katrin Kneipp, Harald Kneipp and Janina Kneipp
Abstract Vibrational signatures provide key information on the molecular composition of matter and on molecular structure and structural changes. Vibrational
transitions in molecules can be probed optically by infrared absorption (IRA) and
Raman scattering (RS). Exploiting local optical fields in the vicinity of plasmonic
nanostructures has revolutionized optics and spectroscopy and opens up exciting new
capabilities, particularly also for vibrational spectroscopy. The basic prerequisites
for plasmon-supported spectroscopy are strongly enhanced and highly confined local
optical fields in the wavelength range applied in the respective spectroscopic method.
Here, we review plasmon supported linear and non-linear vibrational spectroscopies.
Our discussion includes incoherent effects such as surface enhanced Raman scattering (SERS), surface enhanced pumped anti-Stokes Raman scattering (SEPARS),
surface enhanced hyper Raman scattering (SEHRS), and surface enhanced infrared
absorption (SEIRA), as well as coherent Raman techniques such as surface enhanced
coherent anti-Stokes Raman scattering (SECARS) and surface enhanced stimulated
Raman scattering (SESRS). Emphasis will be placed on materials and nanostructures
that efficiently support various vibrational spectroscopic methods. Selected applications of surface enhanced vibrational spectroscopy for chemical probing and sensing
will be discussed.
