我们发现了一种制备金纳米棒和纳米球薄膜的新方法。纳米颗粒膜可以在水溶液和己烷溶液之间的液-液界面处形成，并且几乎是单层的。使用这些薄膜作为 SERS 基底，测量了非共振条件下罗丹明 6G 的表面增强拉曼散射 (SERS) 光谱。实验证明，具有较高纵横比的纳米棒在SERS增强方面更有效。
We found a new method for the preparation of gold nanorod and nanosphere films. The nanoparticle films could be formed at the liquid-liquid interface between aqueous and hexane solutions and were almost monolayers. Surface-enhanced Raman scattering (SERS) spectra of rhodamine 6G under the nonresonance condition were measured using these films as SERS substrates. It is experimentally demonstrated that nanorods with a higher aspect ratio are more effective in SERS enhancement.
