Abstract
We fabricated polymer light-emitting diodes (PLEDs) operating in the ultraviolet (UV) region by a wet-process. The samples consisted of simple bilayer structures. In particular, the electronand hole-transporting materials were doped in the active layers to improve the carrier injection into the active layer. We observed a peaking wavelength of 389 nm was observed in the electroluminescence (EL) spectrum. In addition, the maximum external quantum efficiency was 1.8%.
