Abstract

We report an efficient surface-enhanced Raman scattering (SERS) substrate by utilizing the multi-dimensional plasmonic coupling in Au nanoparticle (NP)-graphene-Ag NP hybrid structures. An ultrasensitive SERS detection with a limit of down to 10(-13) M has been achieved when the sandwiched hybrid film is fabricated on an Ag substrate.

摘要

我们报道了一种通过利用金纳米颗粒（NP）-石墨烯-银纳米颗粒混合结构中的多维等离子体耦合来制备高效表面增强拉曼散射（SERS）基底的方法。当在银基底上制备夹心混合薄膜时，已实现了低至10^(-13) M的超灵敏SERS检测。
