其载流子浓度和迁移率分别为4.3910

-3

和15 cm

-1

在可见光范围内的平均透过率达到85.5%

功函数为5.05 eV。采用AZO作为阳极制备的磷光OLED得到最大亮度为192 400 cd/m

AZO作为OLED的阳极可获得优异的电致发光性能。

Abstract

Al doped ZnO (AZO) thin film is prepared by the double electron beam co-evaporation with an ion-assisted deposition technique. The AZO film shows a carrier density of 4.3910

-3

and an electron mobility of 15 cm

-1

respectively. The AZO thin film has a work function of 5.05 eV

and shows an average visible spectral transmittance of 85.5%. OLED based on AZO anode exhibits a maximum luminance of 192 400 cd/m

and a maximum current efficiency of 83.5 cd/A

which indicates that AZO films can be a promising anode material for organic EL devices.
