Surface-Enhanced Raman Scattering

ByM. Sun

In this chapter, we will review recent studies of the electromagnetic (EM) and chemical mechanisms of surface-enhanced Raman scattering (SERS), including experimental and theoretical studies.

We will begin with the theory of EM field and the computational

methods. Secondly, we will introduce the charge-transfer (chemical) mechanism of SERS, where charge transfer between molecule

and metal, intramolecular charge redistribution and intramolecular

charge transfer will be visualized with the recently developed three-

dimensional (3-D) cube representation. Thirdly, we will discuss

our recently experimental results on SERS. Lastly, we will discuss

recent experimental result on remote SERS excited by propagating

dielectric waveguide along quasi-one-dimensional (Q1D) transition metal oxides, and by propagating plasmonic waveguide along single

Au nanowire with quasi-spherical termini.
