Abstract: At this presentation, we discuss the mechanisms and applications of surface plasmon (SP) coupling and two related processes,

including the Förster resonance energy transfer (FRET) and nanoscale-cavity efiect. The applications cover the efficiency enhancements of a

light emitter and a color converter. From the viewpoint of practical application, we start the discussion with the behavior of the SP resonance of a metalnanostructure. Due to their easy fabrication and low cost, we mainly focus our discussionsabout the SP resonance behaviors of widely

used metal nanoparticles (NPs), including deposited surface metal NP and chemically synthesized metal NP, particularly Ag NP. Then, the

general behaviors of SP coupling, particularly the energy flow behavior in an SPcoupling process, are elucidated. Next, a few examples in applying SP coupling to lighmitting diodes for improving their performances, including internal quantum effciency, electroluminescence, efficiency droop effect, modulation bandwidth, and outpupolarization, are demonstrated. Besides, the roles of SP coupling in enhancing the FRET and hence color conversion efficiency are discussed. Finally, the nanoscale-cavity effectson SP coupling and FRET are studied based on the

nanoscale cavities of subsurface GaNnanopores and surface nanoholes.
