Abstract:

Due to diffraction limit, the optical resolution of a far field light is less than a half of its wavelength, which makes it virtually impossible to “see” subject at the nanoscale. The use of a metallic nanocavity can generate spatially highly confined plasmon with intense field of broad energy distribution. It can break the diffraction limit to visualize a single molecule in real space with the light[1]. Many fascinating properties of the nanocavity plasmon (NCP) have also been found, resulting the plasmonic enhanced stimulating emission[2], coherent energy transfer[3], plasmon induced nonlinear electron scattering[4] and super-high resolution Raman images of single molecules[5]. A new theory that describes the interaction between the localized light and the molecule has been developed[6], which helps to understand the experimental observations and provides also exciting new predictions.
