摘要

采用传输矩阵法对有机电致发光器件（OLED）、微腔有机电致发光器件（MOLED）和耦合微腔有机电致发光器件（CMC）的电致发光光谱（EL）进行了模拟计算。OLED、MOLED和CMC的结构分别为glass/ITO（134 nm）/NPB（74 nm）/Alq

（62 nm）/Al、glass/DBR/ITO（134 nm）/NPB（74 nm）/Alq

（62 nm）/Al和glass/DBR

/filler/DBR

/ITO（134 nm）/NPB（74 nm）/Alq

（62 nm）/Al。通过模拟计算发现:OLED光谱呈宽带发射，主峰峰值位于561 nm，肩峰峰值位于495 nm；MOLED光谱呈单峰窄带发射，峰值位于534 nm；CMC光谱呈双峰窄带发射，峰值分别位于520 nm和556 nm。MOLED光谱的色纯度最高；OLED与MOLED的光谱积分面积基本相同；CMC的光谱积分面积是OLED或MOLED的1.1倍，发光效率最高。结果表明，采用双耦合微腔结构可有效提高OLED的发光效率，改善发光的色纯度。

Abstract

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)/Alq

(62 nm)/Al

glass/DBR/ITO(134 nm)/NPB(74 nm)/Alq

(62 nm)/Al

and glass/DBR

/filler/DBR

/ITO(134 nm)/NPB(74 nm)/Alq

(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.
