Surface plasmon resonance of metal nanostructures is an efficient tool to enhance light–matter interactions on the nanoscale. Plasmon interference further intensifies the increase in local electromagnetic fields, which provides the advantage of being able to manipulate the optical absorption, scattering, and emission of metallic nanomaterials. In this paper, we report plasmonic interference in the hybrids of Ag nanorods and Au nanoparticles (AgNR–AuNP). Specifically, we demonstrate that the transmission of AuNPs is enhanced by ∼90% by tuning the localized surface plasmon resonance (SPR) of the AuNPs to 780 nm, resonant with the longitudinal SPR of AgNR array, efficiently amplifying continuum generation in the near-infrared region. These observations show promise for applications in both passive and active plasmonic nanodevices.
