Surface plasmons is a hotspot of research in recent years. Surface plasmons have some particular characteristics such as electric field localization and electric field enhancement. These characteristics can be used to enhance emission of light-emitting diode. Because of electric field localization, SPs has large density of states when excited. This can influence the radiation rate of exciton and improve the quantum yield The direction of radiation and the efficiency of LED can be controled by appropriate configuration. Many research groups have investigated the physical mechanism of enhance emission using SPs in recent years and get some great results. The development of enhanced emission of light-emitting diode using surface plasmons is reviewed.
