surface plasmons have enjoyed use in spectroscopic fluorescence measurements, but that's about as exciting as chamomile tea at a narcolepsy convention. However, those same surface plasmons have been used by Korean researchers to increase OLED efficiency by 75-percent while also increasing intensity twofold -- and that gets our attention. Note we said "researchers," though; the results were obtained with silver nanoparticles under high vacuum conditions -- in other words, a surface science lab. Although the word is that this technique can be used for flexible OLEDs, we won't be holding our breaths. Heck, at this point, we'd settle for relatively inefficient, inflexible, affordable OLEDs somewhere north of 20-inches.
