- A co-doping host layer 4,4’-N,N’-dicarbazole-biphenyl (CBP) and tris-(8-hydroxyqunoline)aluminum(Alq), was incorporated tris (2-Phenylpyridine) iridium [Ir(ppy)3] doped into host as the emitting layer (EML) based organic light-emitting device. Such a structure helps to increase the energy transfer from host to guest resulting in an improved current efficiency. The highest luminous efficiency of the device with 6:4 of CBP: Alq achieved 11.9 cd/A, which is nearly 4.3 times that of the device with 8:2 of CBP: Alq, and the power efficiency achieved 4.69 lm/W, which is nearly 6.7 times that of the device with 8:2 of CBP: Alq.
