Formation of Nanostructure-controlled Strong Coupling of Porphyrin Molecules and Silver Nanoparticles Using Layered Silicates

The nanostructure control of strong coupling has been less thoroughly investigated in organic semiconductor structures than in resonator structures. We achieved strong coupling by introducing a layered silicate between a silver nanodisk resonator and a porphyrin organic semiconductor, where the porphyrin nanostructure is monomeric and parallel to the silicate surface.
