摘　　要：制做了具有微腔结构的绿色和蓝色有机顶发射电致发光器件。利用Alq3和TBADN:3%DSAPh材料为发光层,Ag为阳极反射层,ITO为腔长调节层,Al/Ag为半透明阴极,电极的透射率在30%左右。通过改变ITO层的厚度,Alq3器件得到了不同颜色的发光光谱,实现了对光谱的调节作用;TBADN:3%DSAPh器件获得了纯度较高的蓝色发光光谱,色坐标为(0.141,0.049),半高宽为17nm发光光谱,实现了窄带发射。文章对微腔顶发射器件的发射强度和发光光谱半高宽的结果进行了分析。The green and blue top-emitting organic light-emitting devices with cavity effect have been fabricated.The Alq3 and TBADN：3%DSAPh were used as emitting material of microcavity OLEDs.Silver was deposited as reflective anode and ITO was deposited as adjustive layer.Aluminum and silver thin films were made as semi-transparent cathode.The transmittance of aluminum and silver（Al/Ag） cathode was about 30%.By changing the thicknesses of ITO,different color was obtaind on Alq3 devices and highly saturated color with Commission Internationale de L＇Eclairage chromaticity coordinates（CIEx,y） of（0.141,0.049） was obtained on TBADN：3%DSAPh devices,full width at half maximym（FWHM） was only 17nm.In this article,the spectral intensity and FWHM of emission in cavity devices also have been studied.
