Paul C. Cross Endowed Lecture in Physical Chemistry Professor George Schatz – Department of Chemistry, Northwestern University “Nanoparticles, SERS and Theory” Silver and gold nanoparticles have a history that dates to the Roman empire and before, as well as detailed work by Michael Faraday in the 1850s. However these particles have been given new life (and applications) in the last 40 years through a number of advances in nanoscience, and especially by the discovery of surface enhanced Raman spectroscopy (SERS) in the 1970s. This talk will provide an overview of these advances, especially as relates to SERS substrates, to single-molecule SERS, to tip enhanced Raman spectroscopy (TERS), and to plasmon chemistry. An emphasis in this talk will be on the use of theory to understand the optical properties of plasmonic materials, including both electronic structure theory and electromagnetics.
