Abstract
Polymer light emitting devices were fabricated by roll lamination using single-walled carbon nanotubes as both anode and cathode. The devices exhibited a low turn-on voltage of 3.8 V, high brightness of 1400 cd/m2 at 10 V and maximum efficiency of 2.2 cd/A at 480 cd/m2. The devices are also highly transparent and exhibited very high flexibility. No failure was observed after bending the devices down to 2.5 mm radius.
