Photochemical Transformation on Plasmonic Nanoparticles Via Resonant Radiated-Induced Heating

Stable coupled interactions between interfaces of plasmonic nanomaterials and electromagnetic fields have governed photophysical processes amplified by light-matter interaction. To illustrate underlying physical mechanisms responsible for chemical activity, plasmon-mediated photocatalysis is delivered through oscillations of quantum energy emitters, resulting in non-radiative process of plasmon decay, fertile to chemical transformation. In presence of heat, electron-driven reduction chemistry is spatially mapped akin to electromagnetic near fields, with nanometric resolution as function of time and electromagnetic field polarization, regardibg to variant plasmonic nanostructures. Resultant localization of reactive regions, determined by thermally-induced-carrier transport from high-field regions, prefaces for efficiency in nanoscale regio-selective surface chemistry.
