Controlling Energy Transfer at the Nanoscale using Plasmonic Near-Fields
Abstract
In this proposal, we seek to develop a new hybrid approach based on bridging atomistic electrodynamics methods with electronic structure theory to explore excitation energy transfer of molecules near plasmonic metal nanoparticles. The advantage of the proposed method is that an atomistic description of the metal nanoparticles is retrained which enables an accurate description of the molecular environment to be included in the simulations. The plasmonic near-field in ultranarrow gaps can significantly enhanced the light absorption and light emitting properties of molecules located in the gap. The collective goal of this proposal is to develop a detailed molecular understanding of the electronic and geometric effects governing excitation energy transfer of molecules arranged in well-defined environments near metal nanoparticles. The proposed theoretical tools address several challenges identified in describing excited state properties of molecules near metal nanoparticles relevant for understanding plasmon assisted energy transfer. Of particular interests to the mission of AFOSR are the fundamental understanding of energy transfer at the nanoscale and potential application of the enhanced fluorescence for next generation optical devices based on enhanced fluorescence.
