Abstract

A yellow flexible top-emission polymer light-emitting diode (TOPLED) was fabricated on cyclic olefin copolymer (COC) substrate. The light-emitting material was phenyl-substituted (p-phenylene vinylene) (HYPPV) polymer. The structure of TOPLED was COC/Ag/PEDOT:PSS/HYPPV/Ca/Ag. The Ag on COC was used as anode and the Ag on Ca was used as cathode. After anode Ag was thermally evaporated on COC substrate, the ultraviolet-ozone (UV-ozone) was treated on surface of anode Ag. The treating time was varied. The optimal treated time was 3 minutes. The luminous efficiency of TOPLED increased 42% with 3 minutes UV-ozone treatment.

通过对柔性聚合物发光二极管的表面处理，提高了发光效率

在环烯烃共聚物(COC)衬底上制备了黄色柔性顶发射聚合物发光二极管(TOPLED)。发光材料为苯基取代(对苯基乙烯)(HYPPV)聚合物。TOPLED的结构为COC/Ag/PEDOT:PSS/HYPPV/Ca/Ag。以银COC为阳极，银Ca为阴极。阳极银在COC衬底上热蒸发后，对阳极银表面进行紫外臭氧处理。治疗时间不同。最佳治疗时间为3分钟。uv -臭氧处理3分钟后，发光效率提高42%。
