我们制备了一种新型的发光化合物（Cu和Mn掺杂的硫化锌）/氧化石墨烯（GO）/甲基丙烯酸缩水甘油酯-co-甲基丙烯酸甲酯聚合物复合材料用于电致发光（EL）器件。我们还证明了EL增强通过添加GO纳米片作为一个相对较高的介电添加剂下交流（AC）电场。在576 nm处的ACEL强度随着几重量%的GO添加到复合物中而增加。电致发光增强的趋势对应于它们的电性能，如介电常数在相关的GO聚合物复合材料。
We fabricated a novel luminescent-compound (Cu- and Mn-doped zinc sulfide)⧸graphene oxide (GO)⧸glycidylmethacrylate-co-methylmethacrylate polymer composite for the electroluminescence (EL) device. We also demonstrated EL enhancement by the addition of GO nanosheets as a comparatively high dielectric additive under alternating-current (AC) electric fields. The ACEL intensity at 576 nm increased with several wt% of GO added to the composite. The tendency of EL enhancement corresponded to that of their electric properties like dielectric constants in the related GO⧸polymer composites.
