| 摘 要： | 基于聚(3,4-乙烯二氧噻吩)-聚苯乙烯磺酸(PE DOT:PSS)/氧化石墨烯(GO)混合溶液,利用旋涂法制 备了高电导率透明阳极,并采用硫酸(H2SO4)浸渍处理的方式,使其导电特性进一步 增强。采用最佳方式 处理的PEDOT:PSS/GO混合薄膜在厚度为40 nm时,其方阻为80 Ω/□,在550 nm时的透过率达到87.7％。 基于表面形貌的AFM图,吸收光谱和拉曼光谱,在少量氧化石墨烯掺杂和硫酸处理后,PSS －和PEDOT+链 相分离,使得PEDOT:PSS的结构发生了变化,提高了混合薄膜的电导率。与ITO和纯PEDOT: PSS分 别作为阳极的OLED器件相比,采用优化的PEDOT:PSS/GO混合薄膜作为阳极时的OLED器件具有 最低 的启亮电压和最高的电流效率,其最大亮度是纯PEDOT:PSS作为阳极的OLED的1.7倍。较高 的透过率, 电导率和HOMO能级,尤其是表面形貌的改变都有利于PEDOT:PSS/GO阳极OLED器件性能的改善 。
