▲ [5a-A410-2] Dissymmetry between left- and right-handed circularly polarized photoluminescence enhancement of plasmonic nanostructures
Keywords:plasmonic chiral nanostructures, photoluminescence enhancement, Dissymmetry
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.
