Paper Abstract

Double emitting layer (yellow and blue) phosphorescent organic light emitting devices (OLEDs) were fabricated using different materials as the interlayer. The structure of the devices is ITO/NPB/(t-bt)2Ir(acac)/interlayer/BCP: FIr6/Bphen/Mg:Ag. Interlayers are mCP, TPBi, and TAPC, respectively. Comparing three kinds of interlayer, the luminescence characteristics of the devices are investigated. The results show that the current efficiency and the brightness are greatly improved because of the application of interlayer. Using the mCP as the interlayer, we obtained the maximum current efficiency of 39 cd/A and the maximum brightness of 18360 cd/m2, the color stability is also be enhanced.
