| Abstract: | The micro-structural, electrical and optical properties as well as half- quantitative micro-compositional analysis of aluminum-doped zinc oxide (ZAO) films were investigated. It was revealed that the polycrystalline film is (002) preferred texture and columnar structure, and the c axis is larger than 0.52000 nm. Nonuniformity of component through micro-zones was also observed. The resistivity and average transmittance in the visible region were measured to be 1.39x10-4-cm and 80.8%, respectively. The optical oscillatory character of ZAO films was verified to impact the electroluminescent (EL) spectra of EL devices. ZAO films were used as the transparent anode to fabricate the organic light emitting devices with a luminance efficiency more than 2 cd/A at a current density 5.38 A/m2. |
