| 摘 要： | 表面等离子体(Surface plasmons,SPs)是近年来国际上研究的一个热点. SPs具有空间局域性,局域场增强等特点,可以用来增强发光二极管(Light-emitting diode,LED)的发光效率.利用表面等离子体场局域性质,在共振时SPs有很高的态密度,这能够影响发光中心的辐射速率,提高发光中心的内量子效率;并且可以制作合适的结构,控制光的出射方向,提高发光二极管的提取效率.近年很多研究小组研究了SPs增强发光效率的物理机理,并得到一些很好的结果,本文对现阶段的研究进展进行综述.

| Abstract: | 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. |
