Coupling between excitons and surface plasmons results in a strongly nonmonotonous behavior of exciton decay rate versus temperature, affected by surface plasmons on both sides of the metal layer. Unlike the photons, surface plasmons are not able to escape the sample; hence, the additional decay channel for excitons appears solely due to the plasmon scattering in metal and metal-dielectric interfaces. Tuning the plasmon frequency, one can control the exciton lifetime and under certain conditions emission efficiency |
