The synthesis and application of silver microtube substrates for quantification by surface enhanced Raman spectroscopy (SERS) is presented in this work. The roughened silver microtubes were prepared by template assisted electrosynthesis method. Using rhodamine 6G as a Raman probe molecule, the silver microtubes were tested for SERS determination, demonstrating a high performance for quantitative analysis with high precision and low data dispersion (%RSD < 3), which is the limiting step in quantitative SERS. This performance can be explained by obtaining a single silver microtube substrate highly homogeneous in SERS activity in the whole surface and with high reproducibility between different synthesis batches.

这项工作介绍了用于通过表面增强拉曼光谱（SERS）进行定量的银微管基板的合成和应用。粗糙的银微管通过模板辅助电合成方法制备。使用罗丹明6G作为拉曼探针分子，对银微管进行了SERS测定测试，证明了其具有用于高精度，低数据分散度（％RSD <3）的定量分析的高性能，这是定量SERS的限制步骤。可以通过获得单个银微管基板来解释此性能，该基板在整个表面上的SERS活性高度均一，并且在不同的合成批次之间具有很高的可重复性。
