Keywords:modal strong coupling, emission properties, nanocavity

Recently, we have elucidated that localized surface plasmon resonance mode of gold nanoparticles and resonance mode of nanocavity show modal strong coupling when gold nanoparticles are placed on a Fabry-Pérot nanocavity formed with a titanium dioxide layer on a gold film, and it exhibits highly efficient light absorption and strong electromagnetic field enhancement effect by strong coupling in a wide wavelength range of visible light. In this study, we report on the emission properties of fluorescence molecules under localized surface plasmon-nanocavity strong coupling regime.
