Abstract


Directional and circularly polarised emission from quantum dots coupled with chiral Ag


nanostructures has been demonstrated. Semiconductor quantum dots were deposited onto the chiral


structures using the Layer-by-Layer deposition technique. Time-resolved photoluminescence


measurements demonstrated a lifetime quenching efficiency of 82%, confirming the strong interaction


between the emitters and the antennas. Angle- and polarisation-resolved photoluminescence


measurements revealed that the chiral nanostructures influence the far-field emission properties of the quantum emitters through dipole coupling. The far-field emission from the quantum dots coupled to the chiral nanostructures displays directionality in the emission pattern and more than 17% circular


polarisation, following the handedness of the chiral structure.
