Plasmonic and dielectric nanocavities for enhancing light/matter interactions and nanolocalized chemistry

Plasmonic nanocavities consisting of metallic nanoparticles allow the concentration of light to the nanoscale. While research has up to this point focused almost entirely on this photonic localization aspect, in this talk I will show that metallic nanostructures also allow for highly confined hot spots of chemical reactivity, involving the transfer of hot electrons generated via plasmon decay. This will enable the rational development of structures for nanolocalized surface chemistry and catalysis.
The second part of the talk will focus on dielectric nanocavities and their applications in surface-enhanced fluorescence emission and nonlinear optics, focusing on nanostructures consisting of GaP, Si, and Ge. New opportunities for these material systems as a complementary platform to plasmonics will be discussed.


The Colloquium Ehrenfestii takes place Wednesday evenings starting at 19:30 hours in the main auditorium of the Oort building. Before the Colloquium, there is a common dinner in the canteen located on the ground floor of the Oort building. This dinner starts at 18:00 hours sharp and is free of charge, under the condition that one attends the colloquium and that one has made a reservation before noon on the Tuesday preceding the colloquium. [Registration may close earlier, when 80 persons have signed up]
