摘要	In this paper, we discuss the influence of different microcavity structures of the organic light-emitting devices(OLEDs) in order to improve the luminescence performance. We use the transfer matrix method to simulate and calculate the electroluminescence spectrum(EL)of the OLED, the microcavity organic light-emitting devices(MOLED) and the coupling microcavity organic light-emitting devices(CMC). And then we compare their EL characteristics. The structures of OLED, MOLED and CMC are glass/ITO(134 nm)/NPB(74 nm)/Alq3(62 nm)/Al, glass/DBR/ITO(134 nm)/NPB(74 nm)/Alq3(62 nm)/Al, and glass/DBR1/filler/DBR2/ITO(134 nm)/NPB(74 nm)/Alq3 (62 nm)/Al, respectively. The simulation results show that, the EL spectrum shape of the OLED has a broad spectrum band with the main peak at 561 nm and the shoulder peak at 495 nm, the MOLED has a narrow EL spectrum with single peak at 534 nm, the CMC has a twin narrow EL spectrum with the peaks at 520 nm and 556 nm respectively. The MOLED has the purest color. The integrated area of the OLED and the MOLED are basically the same. The CMC has the largest integrated area, which is 1.1 times of the former two devices. The simulation results show that CMC structure can be used to improve the luminescence efficiency and the color purity of the OLED. 2020, Science Press. All right reserved.
