Nonlinear Spectroscopies of Nanostructured Surfaces and Interfaces

Abstract

The goal of this project is to explore the nonlinear optical properties, surface-selective spectroscopy, and chemical reactivity of nanoplasmonic structures. The project entails technical development of the double-resonance sum frequency generation (SFG) spectroscopy set-up capable of addressing the vibrational resonances of an adsorbed molecule as well as the plasmon resonance of the metallic nanostructures. Following relocation of the PI and his research group to the Chemistry Department of USC in the summer 2009, the first 3 months of this grant period were spent on building the dual-resonance spectroscopy set-up, in particular (1) the development of the novel tunable narrowband (picosecond) visible source for addressing nanoplasmon resonances synchronized with the broad-band (femtosecond) mid-infrared source for addressing vibrational molecular resonances and (2) re-building of the SFG spectroscopy set-up.
