摘要：
In this paper we present our results concerning the role of 2,9-Dimethyl-4,7-diphenyl-1,10-phenanthroline (bathocuproine, BCP) in OLED structures with emissive layer of Tris-(8-hydroxyquinoline) aluminum (Alq(3)). It is established that instead of the higher working voltage of devices with bathocuproine their current efficiency significantly increased. This higher efficiency indicates strong hole-blocking nature of bathocuproine. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
