Abstract
We report on a new polymer light emitting diode (PLED) based on a blend of immiscible polymers. The device shows high efficiency and current density over a broad range of driving voltage, therefore exhibiting very high brightness. The polymer film morphology plays a very important role in determining the device performance, and it can be controlled by changing the blend ratio as well as the polymers molecular weight. The high performance are discussed in terms of 'barrier free' injection into excitonic states. A predicted lifetime in excess of 10,000 hours has already been achieved, making this device structure an ideal candidate for backlighting and monochromatic application.Keywords
