In this work, we investigate the one-photon photoluminescence from a system consisting of an Ag nanowire on an Au film with a ∼6 nm dielectric spacer that supports a localized resonance known as the gap plasmon mode. Although the Ag nanowire and Au film exhibit weak photoluminescence on their own, t...
