我們研發了一種新型表面增強拉曼散射（SERS）基板，這種基板是在陽極氧化鋁奈米網膜上生長銀奈米粒子。我們發現增加銀沉積量，可以降低SERS強度的相對標準差，從而提高SERS基板的均勻性和品質的一致性。因此，在相近的SERS增強效能下，用較高的銀沉積量所製造出的SERS基板具有較高的商品化價值。

We have developed silver-nanostructures grown on anodic alumina nanomesh films to create new-type substrates for surface-enhanced Raman scattering (SERS). Increased Ag-deposition reduced the relative standard deviation of SERS intensities and thus improved both the uniformity and quality consistency of SERS substrates. Fabrication of SERS substrate with larger Ag surface area under similar SERS enhancement factors is suggested for high throughput in commercial sectors.
