Spontaneous emission, collective phenomena and the efficiency of plasmon-stimulated photo-excitation
Igor E. Protsenko, Alexander V. Uskov, Nikolay V. Nikonorov
We find that the spontaneous and collective emissions have a strong influence on the excitation of two-level absorbers (atoms, molecules) interacting in resonance with the plasmoni…
