Herein, we report the synthesis of a 350 nm Cu nanoparticle array with different period combinations by a method based on a monolayer and have further investigated its surface-enhanced Raman scattering (SERS) properties experimentally. The SERS properties of the 350 nm Cu nanoparticle array were investigated, and the influence of the thickness of the Cu nanoshell was studied. The results demonstrated that the 18 min ion-sputtering deposition can improve the SERS activity in addition to good stability. This study can provide an optimized method for some inexpensive nanomaterials as highly active SERS substrates and a good solution to the interference caused by substrate impurity.
在此，我们报告了一种基于单层的方法合成具有不同周期组合的350纳米铜纳米颗粒阵列，并通过实验进一步研究了其表面增强拉曼散射（SERS）特性。研究了350纳米铜纳米颗粒阵列的SERS特性，并研究了铜纳米壳厚度的影响。结果表明，18分钟的离子溅射沉积除了具有良好的稳定性外，还可以提高SERS活性。本研究可为一些廉价纳米材料作为高活性SERS基底提供优化方法，并为解决基底杂质引起的干扰提供良好方案。
