球形纳米粒子已经被广泛地应用于表面增强拉曼散射.为进一步提高纳米球表面电场,从而提高表面增强拉曼散射信号强度,本文设计了平行隔板纳米球结构.离散偶极子近似计算结果表明,应用平行隔板后,纳米球表面电场得到了大幅度增强,故平行隔板纳米球结构更适合作为表面增强拉曼散射衬底,用于生物分子探测.另外,本文还系统地研究了平行隔板结构参数对整个平行隔板纳米球结构光学性质的影响.
Spherical nanoparticles have been widely used in surface-enhanced Raman scattering.In order to further improve the surface electric field of the nanosphere and thus enhance the signal intensity of surface-enhanced Raman scattering, a parallel-spaced nanosphere structure was designed. The results show that the electric field on the surface of nanosphere has been greatly enhanced after the application of parallel separators, so the nanoshells with parallel separators are more suitable as surface-enhanced Raman scattering substrates for biomolecular detection.In addition, The Influence of Structural Parameters of Parallel Baffles on the Optical Properties of Nanoparticles with Parallel Baffles.
