Abstract

Single layer OLEDs by using poly(9,9-di-n-hexylfluorenyl-2,7-diyl) (PHF) as the electroluminescent (EL) layer were fabricated. This paper reports the effect of doping ratios of organic salt, tetrabutylammonium hexafluorophosphate (TBAPF6) on the turn-on voltage, brightness and the EL spectra of the OLEDs. The PHF:TBAPF6 EL layers with weight ratios of 100:x (x=5, x=10 and x=20) were prepared by spin coating technique using chloroform as solvent. The reduction of turn-on voltage and increment of EL intensity were achieved by increasing the TBAPF6 doping ratio. The ITO/PHF:TBAPF6(100:20)/Al device showed the best performance with turn-on voltage as low as 7 V and the highest brightness at 0.36cd/m 2.
