Abstract
We report here strong dissymmetry between left- and right-handed circularly polarized photoluminescence enhancement (PLE) induced by two-dimensional chiral gold nanostructures, which can be utilized to provide circularly polarized luminescence. We employed the dye molecule IR-125 as an emitter whose photoluminescence was enhanced by a near-field interaction between the chiral plasmon and the molecule. The difference between the PLE factors for left- and right-handed circular polarizations induced by the near-field enhancement was correlated to the dissymmetry of left- and right-handed extinction of the gold nanostructures.
