Top emission organic light emitting diodes with carbon nanotubes (CNTs) as top electrodes were fabricated and characterized. Devices were fabricated on glass substrates with evaporated bottom Al/LiF cathodes, spin coated organic emissive layer and PEDOT-PSS hole injection layer. Transparent thin carbon nanotubes films were deposited on top the emission layer to form the anode by micro-contact printing with a polydimethylsiloxane stamp. A very good device performance was obtained with a peak luminance of 3588 cd/m2 and a maximum current efficiency of 1.24 cd/A. This work shows the possibility for using CNTs as transparent electrodes to replace ITO in organic semiconductor devices. Furthermore, the top emission nature of such devices offers a broader range of applications of CNTs onto any types of substrates. By combining with the solution processed organic materials, it is anticipated the lower cost fabrication will be possible through roll-to-roll manufacture. . © nanoAC . . . . . . . . . .
