We have investigated electrical, optical and structural properties of silver nanowire (AgNW)/zinc oxide (ZnO) transparent conductive bilayer films for optoelectronic applications. The AgNW/ZnO transparent conductive bilayer films were fabricated using spin-coating and facing target sputtering (FTS) method. The spin-coated the AgNW layer has advantages, such as low resistivity and high transmittance in visible range. However, the spin-coated AgNW layers can be oxidized by natural oxygen. Consequently, the conductivity of AgNW layer was strongly decreased. So, an oxidation prevented layer is necessary. The ZnO thin film layer on the Ag NW layer can be prevented oxidation. In addition, the peeling of spin-coated AgNW layer were prevented the deposited ZnO thin film layer. As the results, the sheet resistance and average transmittance in visible range of AgNW/ZnO transparent bilayer thin films exhibited 34.1 ohm/sq. and 83.46%.
我们研究了用于光电子应用的银纳米线（AgNW）/氧化锌（ZnO）透明导电双层薄膜的电学、光学和结构特性。采用旋涂和面对靶溅射（FTS）方法制备了AgNW/ZnO透明导电双层薄膜。旋涂的AgNW层具有诸如低电阻率和在可见光范围内高透射率等优点。然而，旋涂的AgNW层会被自然氧氧化。因此，AgNW层的电导率大幅下降。所以，需要一个防氧化层。AgNW层上的ZnO薄膜层可以防止氧化。此外，沉积的ZnO薄膜层防止了旋涂AgNW层的剥落。结果，AgNW/ZnO透明双层薄膜在可见光范围内的方块电阻和平均透射率分别为34.1Ω/sq和83.46%。
