Abstract:
Upright Ag nanoplates on a nanoparticulate TiO(2) film are oriented on the basis of plasmon-induced charge separation. Polarized visible light removes nanoplates oriented perpendicularly to polarization via excitation of in-plane transverse mode. Polarized near-infrared light removes nanoplates in parallel geometry via excitation of in-plane longitudinal mode.
