摘要 制作了具有微腔结构的蓝色有机顶发射电致发光器件。利用TBADN∶3%DSAPh为发光材料,结构为Ag/ITO/CuPc/NPB/TBADN∶3%DSAPh/Alq3/LiF/Al(Ag)。在玻璃基片上,制备Ag为阳极反射层,CuPc作为空穴注入层,NPB作为空穴传输层,ITO为光程调节层;Al/Ag作为半透明阴极,电极的透射率在30%左右。得到了半高宽仅为17 nm发光光谱,实现了窄带发射。通过改变ITO的厚度,得到了纯度较高的蓝色发光光谱,色坐标为(0.141,0.049),实现了高色饱和度的发射。在文章中,作者研究了微腔器件的发光强度,当选择合适的阴极透射率时可以使发光强度达到最大。根据相关的公式,计算出了发光强度随阴极透射率(或者反射率)变化的近似曲线。 The blue top-emitting organic light-emitting devices with cavity effect have been fabricated.The authors used the TBADN∶ 3% DSAPh as emitting material of blue microcavity OLEDs.The devices consisted of Ag/ITO/CuPc/NPB/TBADN∶ 3% DSAPh/Alq3/LiF/Al(Ag) structure.On a patterned glass substrate,silver was deposited as reflective anode,and copper phthalocyanine(CuPc) layer as HIL and 4'-bis[N-(1-Naphthyl)-N-phenyl-amino] biphenyl(NPB) layer as HTL were made.Aluminum and silver thin films were made as semi-transparent cathode.The transmittance of aluminum and silver(Al/Ag) cathode was about 30%.In EL spectrum,the full width at half maximum(FWHM) was only 17 nm.By changing the thicknesses of ITO,highly saturated color with Commission Internationale de L'Eclairage chromaticity coordinates(CIEx,y) of(0.141,0.049) was obtained. In the present article,the emission intensity of spectrum was studied.An appropriate cathode transmittance will result in maximal emission intensity.By using the formula of microcavity,the approximative curve that describes the change of emission intensity with cathode transmittance(or reflectance) was figured out.
