摘要：

We demonstrated that the efficiency of green organic light-emitting diodes (OLEDs) was improved by co-doping with hole transport material, N'-bis-(1-naphyl)-N,N'-dipheny1-1,1'-biphenyl-4,4 '-diamine (NPB) and electron transport material, bis(2-methy1-8-quninolinato)-4phenylphenolate aluminum (BAlq), into emitting layer. Co doping with NPB and BAlq can improve charge balance which makes it possible to enhance device efficiency. The maximum luminous and quantum efficiency of BDAT-P doped device was measured to be 5.56 cd/A and 1.99 %, respectively. Device co-doped with NPB, BAlq and BDAT-P resulted in the most efficient device, in which maximum luminous and quantum efficiency were 8.36 cd/A and 3.19 %, respectively.
