CuAu alloy nanowires were prepared by a solid-state ionics method under a direct current electric field (DCEF) using fast ionic conductor RbCuClI films. The surface morphology, chemical composition and crystal structures of the CuAu alloy nanowires were characterized by scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and X-ray diffraction (XRD), respectively. Raman enhancement performance of the CuAu alloy nanowires substrates was detected by Rhodamine 6G (R6G) aqueous solutions as probe molecules. Long-range disorder and short-range order CuAu alloy nanowires with the length of 1 cm were prepared by a solid-state ionics method. The nanowires were bamboo-shaped and the diameters of nanowires ranged from 40 to 100nm. The molar ratio of Cu to Au is 16:1. The crystal structure of the CuAu alloy nanowires is crystallized. A part of Cu and Au formed AuCu alloy structure. The limiting concentrations of R6G for the prepared CuAu alloy nanowires SERS substrates is 10mol/L.
CuAu 合金纳米线通过直流电场（DCEF）下的固态离子学方法，使用快速离子导体 RbCuClI 薄膜制备。通过扫描电子显微镜（SEM）、能量色散光谱仪（EDS）和 X 射线衍射（XRD）分别对 CuAu 合金纳米线的表面形貌、化学成分和晶体结构进行了表征。通过 Rhodamine 6G（R6G）水溶液作为探针分子检测了 CuAu 合金纳米线基底的拉曼增强性能。通过固态离子学方法制备了长度为 1 厘米的长程无序和短程有序的 CuAu 合金纳米线。纳米线呈竹状，纳米线的直径范围为 40 至 100nm。Cu 与 Au 的摩尔比为 16:1。CuAu 合金纳米线的晶体结构是结晶的。一部分 Cu 和 Au 形成了 AuCu 合金结构。所制备的 CuAu 合金纳米线 SERS 基底的 R6G 的极限浓度为 10mol/L。
