abstract = "We present highly efficient red and green phosphorescent devices comprising only two organic layers. Novel host materials having good electron transporting and new narrow band-gap fluorescent characteristics lead to the fabrication of simplified high efficiency devices. The driving voltage value of 3.3 V to reach luminance of 1000 cd/m2 is reported in simple bi-layer red and green phosphorescent OLEDs, respectively. The maximum current- and power-efficiency values of 38.30 cd/A and 46.60 lm/W are demonstrated in this green device. The current and power efficiencies of bi-layered red PHOLED are 9.38 cd/A and 11.72 lm/W. Results reveal a practical way to fabricate highly efficient truly bi-layer organic devices for trouble-free manufacturing processes.",
