摘要：
We report the incorporation of lithium fluoride doped 4, 7-diphenyl-1, 10-phenanthroline (Bphen:LiF), Al, and molybdenum trioxide (MoO3) which is utilized to form the charge injection buffer layer in single-unit organic light-emitting devices (OLEDs). This hybrid buffer layer at the anode/organic interface was found to be very effective, which increased accumulation of holes at the NPB-buffer interface to improve the balance of the carrier injection. Both the maximum current efficiency and maximum power efficiency of the device were improved by 1.3 times. The results strongly indicate that carrier injection ability and balance shows a key significance in device performance. © 2017, Science Press. All right reserved.
