Al-doped ZnO (AZO) and Ag–Ti films were successfully deposited on glass substrates by multi-target magnetron sputtering to form the high transparent AZO/Ag–Ti/AZO multilayer. The optical, electrical properties and lifetime performance were investigated at various AZO and Ag–Ti thicknesses. As the AZO thickness was fixed at 10nm and Ag–Ti thickness was varied between 6 and 22nm, it can be found that AZO10nm/Ag–Ti10nm/AZO10nm possessed good conductivity and highest transmittance in visible region. Then an AZO thickness adjustment of 10–90nm was performed. With increasing AZO thickness from 10 to 70nm, the transmittances of AZO10–70nm/Ag–Ti10nm/AZO10–70nm films were all above 80% in the visible region and optimal transparency can be reached at AZO thickness of 70nm. Although the conductivity in AZO/Ag–Ti/AZO films was decreased with increasing Ag–Ti thickness, the resistivity of 4.95×10−4Ω-cm in AZO70nm/Ag–Ti10nm/AZO70nm was still acceptable. From the lifetime tests under normal circumstance, these multilayers almost showed the same transmittance and resistivity from 0 to 90days. Furthermore, the AZO70nm/Ag–Ti10nm/AZO70nm exhibits the highest figure of merit of 8.93×10−3Ω−1, indicating that the multilayer has high potential in optoelectronic applications.
