Relating Nanoparticle Geometry and Terahertz Reflectivity

Research output: Chapter in Book/Conference paperConference paper

Abstract

We conducted terahertz thermometry using a terahertz time-domain spectroscopy system (THz-TDS) with several different gold nanoparticle sizes and shapes, and surface plasmon resonance (SPR) induced by a 520nm laser. The change in terahertz reflectivity due to induction of SPR was related to nanoparticle geometry and is consistent with temperature changes measured by infrared imaging. This work allows for optimization of terahertz thermometry techniques via the design of appropriate nanoparticles.
