A quantitative correlation between plasmon resonance and surface enhanced Raman scattering (SERS) signals is revealed by using a novel active plasmonic method, that is, a deformable nanoplasmonic membrane. A single SERS peak has the maximum gain at the corresponding plasmon resonance wavelength, which has the maximum extinction product of an excitation and the corresponding Raman scattering wavelengths.
通过使用一种新的主动等离子体方法，即可变形的纳米等离子体膜，揭示了等离子体共振和表面增强拉曼散射（SERS）信号之间的定量相关性。单个 SERS 峰在相应的等离子体共振波长处具有最大增益，该波长具有最大的激发和相应的拉曼散射波长的消光产物。
