Figure 2From: The coupling between localized surface plasmons and excitons via Purcell effectSchematic diagram of the electron–hole recombination and coupling mechanism between LSPs and excitons in SiN x . The interaction between LSPs and excitons can be treated as a two-step process: (1) the excitons transfer their energies to the LSP modes; (2) the energy from the LSP mode out-couples to radiated photons.Back to article page
