Abstract

The authors report the enhancement of efficiency of polymer light-emitting diodes (PLEDs) in the study. According to the experimental results, we find that PLEDs, fabricated on irradiated indium-tin-oxide surfaces by KrF excimer laser, with an organic layer between the cathode and the emitting layer may lead to the improvement of charge-injection balance and prevention of cathode metal quenching, resulting in a remarkable increase in external quantum efficiency.
