Plasmon-Sampled Surface-Enhanced Raman Excitation Spectroscopy

Plasmon-Sampled Surface-Enhanced Raman Excitation Spectroscopy 

The current widespread interest in size-dependent optical properties of nanomaterials is a consequence of their many applications in research areas such as chemosensors, biosensors,nanoparticle optics, and surface-enhanced spectroscopy. Recently, interest in surface-enhanced Raman spectroscopy (SERS) 

Surprisingly, in the 25 years since the discovery of the SERS effect, there has never been a detailed comparison of the localized surface plasmon resonance (LSPR) spectra of highly ordered, structurally well-defined, nanoparticle surfaces and the surface-enhanced Raman excitation spectra (SERES) even though they are intimately linked through the electromagnetic (EM) enhancement mechanism. There are more than 4000 papers concerning SERS and its many applications however, less than 30 of these address SERES. The paucity of SERES data in the literature is a consequence of the difficulty of SERES experiments, its typically low data point density, and, therefore, its low information content.
