The Ohio University NQPI Virtual Nanoforum presents Eva Yazmin Santiago Santos discussing “Optical and Photothermal Properties of Plasmonic Nanomaterials” on Thursday, Nov 19, at 4:10 p.m. via Microsoft Teams.

Santos is a graduate student in Physics & Astronomy and the Nanoscale Quantum Phenomena Institute (NQPI).

Abstract: The study of the optical and photothermal properties of plasmonic nanomaterials is part of the basis of modern nanoscience and nanotechnology. In particular, metal nanoparticles are great candidates because they exhibit strong absorption and scattering of electromagnetic radiation at the nanoscale. This originates from localized surface plasmon resonances (LSPRs) present in these materials. The strong interaction between a plasmonic nanocrystal and light and its great dependency of the shape, size, material and environment of the system allows the manipulation of its properties.  As part of our research, we study the local heating of plasmonic nanoparticles and the enhancement of the electric field around them. We also developed a formalism to describe the generation of hot electrons in a plasmonic nanocrystal with an arbitrary shape.
