摘要：

We have developed efficient organic electroluminescent (EL) devices using a phosphorescent material, tris(2-phenylpyridine) iridium, Ir(ppy)(3), as as an emitter material and a polymer buffer layer, tetraphenyldiamine-containing poly(arylene ether sulfone) (PTPDES) doped with tris(4-bromophenyl) aminium hexachloroantimonate (TBPAH) as an electron acceptor. In this device, a high external quantum efficiency of 21.6% and a luminous efficiency of 82 lm/W (77 cd/A) at 3,0 V were obtained. These high efficiencies can be explained by high quantum efficiency due to phosphorescent Ir(ppy)(3) and high luminous efficiency realized by the use of the polymer buffer layer.
