Optical nanoantenna is a key component in plasmonic circuitry, which can receive or transmit an electromagnetic field in the near field of an object (nanomaterials). It has wide range of applications including surface‐enhanced Raman scattering (SERS), photocatalytic reactions, remote SERS, solar cell, plasmonic nanoscopy, and quantum plasmonics. The main challenges in optical nanoantenna research include both fundamental understanding of the underlying physics and issues related to fabrication of low cost, high throughput nanostructures beyond the diffraction limit. The nanoscale feature size of optical antennas limits our ability to design, manufacture, and characterize their resonant behavior. This review investigates the fabrication methods and SERS applications of optical nanoantenna.

用于光束和表面增强拉曼光谱的光学纳米天线

光学纳米天线是等离激元电路中的关键组件，它可以在物体（纳米材料）的近场中接收或传输电磁场。它具有广泛的应用，包括表面增强拉曼散射（SERS），光催化反应，远程SERS，太阳能电池，等离子纳米技术和量子等离子技术。光学纳米天线研究的主要挑战包括对基本物理学的基本理解以及与制造超出衍射极限的低成本，高通量纳米结构有关的问题。光学天线的纳米级特征尺寸限制了我们设计，制造和表征其谐振行为的能力。本文综述了光学纳米天线的制备方法和SERS应用。
