中文摘要：

采用旋涂法对PEDOT∶PSS薄膜进行了酸处理,研究了不同方法处理PEDOT∶PSS薄膜对器件ITO/酸处理PEDOT∶PSS/NPB/Alq3/Li F/Al性能的影响。实验结果表明：用盐酸（草酸）处理PEDOT∶PSS薄膜时,以0.75 mol/L的盐酸（草酸）在120℃下退火15 min时性能更好,最大电流效率达到4.28 cd/A。并且盐酸、草酸处理PEDOT∶PSS薄膜制备器件比未处理PEDOT∶PSS薄膜制备器件的电流效率明显提高了34%。

英文摘要：

A set of organic light-emitting diodes were fabricated with a structure of ITO/acid-treated PEDOT： PSS/NPB/Alqa/LiF/A1. The optical and electrical properties were studied. It is found that OLED device with PEDOT： PSS films treated by 0.75 mol/L HCI（ C2H204） annealed at 120 ℃ for 15 min exhibits a better performance with a maximum luminous efficiency of 4.28 cd/A at 100 mA -2 cm The luminous efficiency of OLED with CEHEO4-treated PEDOT：PSS is obviously increased by 34% than those no untreated.
