Abstract:In this study the performance of organic light-emitting diodes (OLEDs) are enhanced significantly, which is based on dual electron transporting layers (Bphen/CuPc). By adjusting the thicknesses of Bphen and CuPc, the maximal luminescence, the maximal current efficiency, and the maximal power efficiency of the device reach 17570 cd/m2 at 11 V, and 5.39 cd/A and 3.39 lm/W at 3.37 mA/cm2 respectively, which are enhanced approximately by 33.4%, 39.3%, and 68.9%, respectively, compared with those of the device using Bphen only for an electron transporting layer. These results may provide some valuable references for improving the electron injection and the transportation of OLED.
Keywords:organic light-emitting diodes  dual electron transporting layers  CuPc
