Abstract: 

Electrochemical Surface Enhanced Raman Scattering or “EC-SERS” increases the sensitivity of the Raman signal by several orders of magnitude, helps to get the mechanistic and dynamic information on the electrochemical interfaces at the molecular level. Unlike normal Raman spectroscopy, all EC-SERS active system must process nanostructures and the SERS activity is critically dependent on configuration and composition of nanostructured as well as applied potential.

In my seminar, I will first briefly discuss about Raman scattering and devolvement of EC-SERS. I will briefly describe mechanism of enhancement in intensity of EC-SERS. Finally, I will discuss strategies to measure Raman scattering signal during Spectro-electrochemical measurement, which exploit the SERS effect and their applications.
