Enhanced Photophysical Processes in Controlled Electromagnetic Nanoenvironments

摘要

The objectives of this grant 'Enhanced Photophysical Processes in Controlled Nanoenvironments' were to investigate the role of electromagnetic nanoenvironments on fundamental photophysical processes in molecular species. By systematically designing tunable plasmonic nanostructures such as nanoshell dimers, small clusters, extended monolayer arrays of nanoparticles, and other hybridized structures, controlled electromagnetic environments can be created. The enhanced fields generated in these environments is then used to study photophysical processes such as surface enhanced Raman scattering (SERS), Fluorescence enhancement and surface enhanced infrared absorption (SEIRA) of molecules placed in these enhanced fields. All the objectives stated were successfully achieved. Below is a brief description of the particular achievements. A complete list of publications is attached at the end.
