Ag nanoparticles sputtered on silicon wafer are used as masks for the fabrication of silicon columns by ion etching, which induces the growth of the inclined Ag nanorod by inclined Ag sputtering. V-shaped and Z-shaped Ag nanorods can be obtained by varying incline angles and deposition times. SERS detection and FDTD simulation are used to compare and investigate the enhanced electromagnetic coupling of incline nanorod arrays with different shapes in three-dimensional space, which indicates that Z-shaped nanorods show good SERS properties. The Z-shaped Ag nanorod array is used as a SERS substrate for the detection of thiabendazole with a concentration down to 10 M.
溅射在硅片上的银纳米颗粒被用作通过离子蚀刻制造硅柱的掩膜，离子蚀刻通过倾斜的银溅射诱导倾斜的银纳米棒生长。通过改变倾斜角度和沉积时间可以获得V形和Z形银纳米棒。利用表面增强拉曼散射（SERS）检测和时域有限差分（FDTD）模拟来比较和研究三维空间中不同形状的倾斜纳米棒阵列的增强电磁耦合，结果表明Z形纳米棒具有良好的SERS性能。Z形银纳米棒阵列被用作SERS基底，用于检测浓度低至10⁻⁸ M的噻苯达唑。
