Organic electroluminescent (EL) devices with one layer of 1,1 bis( p diethyl aminophenyl) 4,4 diphenyl 1, 3 (DEAB) doped with different quantities of poly(methylmethacrylate) (PMMA) (DEAB/PMMA) as the EL ...Organic electroluminescent (EL) devices with one layer of 1,1 bis( p diethyl aminophenyl) 4,4 diphenyl 1, 3 (DEAB) doped with different quantities of poly(methylmethacrylate) (PMMA) (DEAB/PMMA) as the EL emitting layer, sandwiched between indium/tin oxide (ITO) and aluminum electrodes, have been fabricated by spin coating onto ITO. We found that there is an optimum doping ratio of DEAB to PMMA in the emitting layer for enhancing the EL intensity and efficiency of DEAB/PMMA devices.展开更多
