摘　　要：用微腔调色法来实现有机发光器件的三基色,有利于减少光损失,并提高器件的色饱和度和效率.以多波长的白光器件为基构成了微腔顶发射器件.顶发射器件以Ag作为全反射阳极,ITO为光程调节层,Al/Ag为半透明复合阴极,Alq:DCJTB/TBADN:TBPe/Alq:C545为白光发光层.通过调节ITO厚度,改变微腔光程以及器件的颜色,分别得到红、蓝、绿三基色的器件,器件发光峰值分别为475,538和603nm,色坐标分别为(0.133,0.201),(0.335,0.567)和(0.513,0.360).半高宽分别为30,48,70nm.RGB pixel generation by microcavity top-emitting organic light-emitting diodes （TOLEDs） is beneficial to both the reduction of the light loss and the improving the color purity and efficiency. Based on the multi-emitting layers, white organic light-emitting diodes （OLEDs） and microcavity TOLEDs were prepared. TOLEDs were made using Ag/ITO as the reflector and adjusting layer, Al/Ag as the semi-transparent cathode, and Alq：DCJTB/TBADN：TBPe/Alq：C545 as white light emitting layer. By adjusting the thickness of ITO, optical length of cavity the colour of the device can be changed, so the RGB tricolor devices are obtained. The peak wavelengths are 476,539 and 601 nm, the commission Internationale d＇ Eclairage （CIE） coordinates are （0. 133,0. 201 ）, （0.335,0.567） and （0.513,0.360）, and the FWHM are 32,50 and 73 nm for Blue, Green and Red,respectively.
