Abstract

We report the effect of polystyrene nanolayer on electron injection on the polymer light-emitting diodes (PLEDs) in which hole is major charge carrier. Especially, when a ∼10nm-thick polystyrene layer was employed, the device gave two orders a magnitude higher external quantum efficiency than that of the one without an insulting nanolayer. This enhancement may result from the dramatic lowering of the effective barrier height for electron injection to the emmiting layer.
