This Account describes a new paradigm for the relationship between the geometry of metallic nanostructures and their optical properties. While the interaction of light with metallic nanoparticles is determined by their collective electronic or plasmon response, a compelling analogy exists between plasmon resonances of metallic nanoparticles and wave functions of simple atoms and molecules. Based on this insight, an entire family of plasmonic nanostructures, artificial molecules, has been developed whose optical properties can be understood within this picture: nanoparticles (nanoshells, nanoeggs, nanomatryushkas, nanorice), multi-nanoparticle assemblies (dimers, trimers, quadrumers), and a nanoparticle-over-metallic film, an electromagnetic analog of the spinless Anderson model.
本综述描述了金属纳米结构的几何形状与其光学性质之间关系的一种新范式。虽然光与金属纳米颗粒的相互作用由其集体电子或等离子体响应决定,但金属纳米颗粒的等离子体共振与简单原子和分子的波函数之间存在引人注目的类比。基于这一见解,已经开发出了一整个等离子体纳米结构家族,即人工分子,其光学性质可以在这一框架内得到理解:纳米颗粒(纳米壳、纳米蛋、纳米套娃、纳米米)、多纳米颗粒组件(二聚体、三聚体、四聚体)以及一种金属膜上的纳米颗粒,它是无自旋安德森模型的电磁类似物。
