摘要：
The electrical and optical properties of electrophosphorescent organic light-emitting diodes (OLEDs) with modified hole blocking layer (HBL) were investigated. Well-known 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP) HBL is mixed with electrophosphorescent host material (4,4'-N,N'-dicarbazole-biphenyl: CBP) or electrophosphorescent dopant material (fac-tris(2-phenylpyridine) iridium: Ir(ppy)(3)) or both. The highest external quantum efficiency was obtained in the device with BCP-CBP-Ir(ppy)(3) mixed HBL and we attribute this result to the additional charge recombination in mixed-HBL.
