Abstract

Plasmonic nanostructures can be used as nanoscale heat sources under light illumination. The heat generation leads to the increase of local temperature and thus the change of permittivities of both the plasmonic metals and surrounding dielectric media due to the thermo-optic effect. In this talk, I will present our research on using the photothermal properties of silver nanowires to modulate propagating surface plasmons and using gold nanorods with tunable surface plasmon resonances to demonstrate resonant scattering enhanced photothermal imaging.
