中文摘要：
以Ag／ITO为全反射阳极，以Al/Ag为半透明复合阴极，制备了绿色、蓝色两种微腔结构顶发射有机发光器件，研究了微腔效应对顶发射器件颜色的影响，通过调节光程，实现了用同一种有机发光层制备出不同波长的发射．Alq基顶发射器件得到波长峰值从500nm到584nm的不同颜色的器件，发光光谱半高宽由传统器件的100nm窄化到20—40nm，最高电流效率1．77ed/A．蓝光顶发射器件发光峰值从464nm变化到532nm，半高宽由传统器件的65nm窄化到17—21nm，并得到色坐标为（0．141，0．049）的深蓝色顶发射有机发光器件．
英文摘要：
Top-emitting organic light-emitting devies （TOLEDs） have been constructed with Ag/ITO reflective anode and LiF/Al/Ag semi-transparent cathode . The cavity effect have been researched by using Alq and TBADN ：TBPe as emitting layers respectively. Different colors from the same emitting layer have been realized by changing the thickness of ITO. For Alq-based TEOLEDs, the full width at half maximum（FWHM） was narrowed to 20-40 nm from the 100 nm of bottom-emitting organic light-emitting devices （ BEOLEDs）. the EL peak was shifted from 500 nm to 584 nm by changing the thinckness of ITO. The maximun current efficiency of the TOLEDs is 1.77 cd/A, which approaches to the 1.8 cd/A of tranditional devices. For TBADN： TBPe-based devices, the FWHM was narrowed to 20 from BEOLEDs＇s 65 nm. the EL peak was shifted from 464nm to 532 nm by changing the thinckness of ITO, and navy blue with CIE coordinates x = 0.141, y = 0.049 have been obtained by TBADN： TBPe-based TEOLEDs with cavity effect.
