Single-walled carbon nanotube (SWNT) films on flexible PET (polyethyleneterephthalate) substrates are used as transparent, flexible anodes for organic light-emitting diodes (OLEDs). For polymer-based OLEDs having the structure: SWNT/PEDOT-PSS:MeOH/TFB (poly(9,9-dioctylfluorene-co-N-(4-butylphenyl)diphenylamine)) + TPD-Si(2) (4,4'-bis[(p-trichlorosilylpropylphenyl)phenylamino]biphenyl) /BT (poly(9,9-dioctylfluorene-co-benzothiadiazole))/CsF/Al, a maximum light output of 3500 cd/m(2) and a current efficiency of 1.6 cd/A have been achieved. The device operational lifetime is comparable to that of devices with Sn-doped In(2)O(3) (ITO)/PET anodes. The advantages of this novel type of anode over conventional ITO are discussed.
柔性聚对苯二甲酸乙二酯（PET）基板上的单壁碳纳米管（SWNT）薄膜被用作有机发光二极管（OLED）的透明柔性阳极。对于具有以下结构的聚合物基OLED：SWNT/聚（3,4-乙撑二氧噻吩）-聚苯乙烯磺酸盐：甲醇/TFB（聚（9,9-二辛基芴-co-N-（4-丁基苯基）二苯胺））+TPD-Si(2)（4,4'-双[（对三氯硅烷基丙基苯基）苯基氨基]联苯）/BT（聚（9,9-二辛基芴-co-苯并噻二唑））/氟化铯/铝，已实现最大光输出为3500 cd/m²，电流效率为1.6 cd/A。该器件的工作寿命与具有掺锡氧化铟（ITO）/PET阳极的器件相当。讨论了这种新型阳极相对于传统ITO的优点。
