Title: Application of STEM/EELS to Plasmon-Related Effects in Optical Spectroscopy

Abstract

The last decade has seen an explosion in the study of plasmonic materials, with current applications including surface-enhanced spectroscopy, imaging beyond the diffraction limit, solar energy harvesting, and ultrasensitive detection. This proposal utilizes electron energy loss spectroscopy (EELS) in a scanning transmission electron microscope (STEM) to explore the near-field enhancements encountered upon excitation of the localized surface plasmon resonance. In particular we have studied Fano interferences using optical and electron energy-loss spectroscopies (EELS). Single silver nanocubes were utilized in this study due to the substrate-mediated hybridization of the primitive dipolar and quadrupolar plasmon modes that give rise to the Fano phenomenon. The cube at substrate system provides a unique opportunity to study the plasmonic energy transfer from metallic nanoparticles to neighboring materials, which is an essential component of plasmon-enhanced solar harvesting devices.
