The fabrication of a light-emitting device based on a composite consisting of cadmium sulfide nanoparticle, poly(vinylalcohol), and ruthenium 2,2'-bipyridyl complex is reported. The electroluminescence spectrum of this composite is similar to the combination of the emission from ruthenium complexes and cadmium sulfide. A stable electroluminescence at low threshold voltage (4 V), with a brightness of 680 cd/m2 and an external quantum efficiency of approximately 0.2% was achieved. it was demonstrated that the cadmium sulfide nanoparticles were able to improve the performance of the device and enhance the electron carrier mobility as compared to the device based on pure ruthenium complex.
报道了一种基于由硫化镉纳米颗粒、聚乙烯醇和钌2,2'-联吡啶配合物组成的复合材料的发光器件的制备。该复合材料的电致发光光谱类似于钌配合物和硫化镉发射的组合。在低阈值电压（4 V）下实现了稳定的电致发光，亮度为680 cd/m²，外部量子效率约为0.2%。结果表明，与基于纯钌配合物的器件相比，硫化镉纳米颗粒能够改善器件性能并提高电子载流子迁移率。
