Abstract

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-Si2 (4,4′-bis[(p- trichlorosilylpropylphenyl)phenylamino]biphenyl) /BT (poly(9,9-dioctylfluorene- co-benzothiadiazole))/CsF/Al, a maximum light output of 3500 ca/m2 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 In2O 3 (ITO)/PET anodes. The advantages of this novel type of anode over conventional ITO are discussed.
