Schematic diagram of the electron–hole recombination and coupling mechanism between LSPs and excitons in SiNx. 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.
