Abstract The present paper uses the R-4B as phosphor dopant, the main body was CBP, regulation carrier composite layer was BCP, and the device structure was ITO/MoO3 (30)/NPB (40)/TCTA (10)/CBP∶R-4B(6%)(15)/BCP(x)/CBP∶R-4B(6%)(15)/BCP(10)/Alq3(40)/LiF/Al. In the device, x was the thickness of the BCP with five different thickness of the device. At the same time, another contrast device was made, which had been optimized at MoO3 without regulated BCP layer. The result shows that the luminous area was 1.18 cm2, BCP was 4, MoO3 was 30 nm, its performance was the best, light voltage was 4 V, maximum efficiency was 18.9 cd·A-1, its corresponding EL main peak was at 612 nm, and color coordinates was (0.643, 0.353), getting stable and high efficient red phosphor OLED devices.
