A significant increase in the quantum efficiency of an organic red- and blue-light-emitting diode was achieved through coupling with localized surface plasmons of Au nanorods and nanospheres, respectively, embedded on the substrate anode. We used Alq3 as an emission layer. The fabricated diode structure consists of an indium tin oxide (ITO) anode, a Cu phthalocyanine (CuPc) hole transport layer, an Alq3 electron transport layer, a LiF electron injection layer, and an Al cathode. We observed at most a 20-fold increase in the intensity of molecular fluorescence compared with that of a conventional diode structure.

通过分别与嵌入在衬底阳极上的Au纳米棒和纳米球的局域表面等离子体耦合，显著提高了有机红色和蓝色发光二极管的量子效率。我们使用Alq3作为发射层。该二极管结构由ITO阳极、CuPc空穴传输层、Alq3电子传输层、LiF电子注入层和Al阴极组成。我们观察到，与传统的二极管结构相比，分子荧光强度至多增加了20倍。
