Photochemical Transformation on Plasmonic Nanoparticles Via Resonant Radiated-Induced Heating

Stable coupled interaction between the interfaces of plasmonic nanomaterials and electromagnetic fields have governed photophysical processes amplified by light-matter interaction. Said interaction recently entertained a breadth of study in photochemical catalysis as optically excited plasmons of the nanoparticle metallics are keen to chemical transformations on their sufaces. To illustrate underlying physical mechanisms responsible for observed 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. Thermalization, the parameter by which quantum emitters are chemically adjusted, bodes well for surveyance of the energy transfer and dissipation into the environment by nanoparticle phonon modes. 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 with regard to variant plasmonic nanostructures. The resultant localization of reactive regions, determined by thermally-induced-carrier transport from high-field regions, prefaces way for efficiency in its nanoscale regio-selective surface chemistry.
