We demonstrate the potential of combining plasmonic Bragg grating structures, with the scattering effect of a rough Al layer to tune SERS enhancement in the visible region. Novel Al-based substrates with good analytical reproducibility and enhancement factors in the range of 107-109 are produced by a scalable procedure which meets the development of producing sustainable SERS platforms.
我们展示了将等离子体布拉格光栅结构与粗糙 Al 层的散射效应相结合，从而在可见区域中调谐 SERS 增强的潜力。通过一种可扩展的程序，生产出了具有良好分析重现性和增强因子在 107-109 范围内的新型基于 Al 的基底，该程序满足了可持续 SERS 平台的发展需求。
