中文摘要：
使用典型天蓝色磷光材料FIrpic作为磷光金属微腔有机发光器件（OLED）的发光层，以高反射的Al膜作为阴极顶电极和半透明的Al膜作为阳极底电极，采用空穴和电子注入层MoO3和LiF，制备了结构glass／Al（15nm）／MoO3（znm）／NPD（40nm）／mCP：Flrpic（30Ftm，7％）／BCP（20nm）／Alqa（20nm）／LiF（1nm）／Al（150nm）的底发射磷光金属微腔OLED，微腔OLED正方向电致发光（EL）光谱的中心波长为468nm，半波宽（FWHM）约为24nm，色坐标为（0．14，0．15），其发光波长得到调制，光谱得到窄化。理论模拟得到微腔OLED的发光增强因子与实际光谱吻合。
英文摘要：
The sky-blue phosphor Flrpic-based electrophosphorescent bottom-emitting metallic microcavity organic lighvemitting device （OLED） employs a structure of glass/Al（15 nm）/MoO3 （x nm）/NPD （40 nm）/ mCP：FIrpie（30 nm,7%）/13CP（20 nm）/Alq3 （20 nm）/LiF（1 nm）/Al（150 nm）,using MoO3 and LiF as efficient hole and electron injection layers, respectively. The cavity structure consists of the highly reflective Al cathode and the semitransparent Al anode. The emission spectrum of the microcavity OLED is centered at 468 nm with a full width at half maximum （FWHM） of 24 nm,and CIE color coordinates are x=0. 14 and y=0.15. It＇s indicated that the spectrum is modulated and narrowed. Theoretical simulations of the enhancement factor of the microcavity OLED agree with experimented results well.
