Paper Abstract

The influence of various red doping materials on the photoelectric performance of highly efficient organic light emitting diodes (OLEDs) were systematically investigated. The multilayerd red-light OLEDs fabricated in this work have the structure of ITO/m-MTDATA/NPB/Alq3:MGAg. Three different doping materials, including 4-(dicyanomethylene)-2-t-butyl-6(1,1,7,7-tetra-methyl-ljulolidyl-9-enyl)-4H-pyran, 4-Dicyanomethyl-lene-2-methyl-6-[2-(2,3,6,7-tetrahydro-1H,5H-benzo quinoliz-in-8-yl)vinyl]4H-pyran) (DCM2), and Nile Red (NIR), were adopted. Compared with the various red-doped OLEDs, the highest luminance occureed in DCM2-doped OLED. Evidence showed that the co-existence of exciton energy transfer and carrier trapping processes in DCM2-doped OLED is the main reason leading the highest luminance occurred in that device.
