Abstract

Plasmonic nanoparticles exhibit dramatic changes in optical properties depending on their spatial organization. Therefore, the ability to precisely control their assembly structure is important for both fundamental understanding and practical applications. In this personal account, we describe a templated surfactant-assisted seed-growth method to synthesize core–shell-type gold nanoparticle assemblies with controllable surface morphologies and optical properties. This approach provides a simple procedure for simultaneous growth and assembly of metal nanoparticles on polymer templates, producing well-defined nanostructures such as spiky nanoshells and raspberry-like metamolecules with useful and interesting optical properties, such as strong and uniform surface-enhanced Raman scattering and metamaterial properties. We discuss the factors that control the morphology and collective properties, describe the design rules acquired from the system, and suggest future directions of this research area.

通过模板表面活性剂辅助种子生长法获得形态各异的金纳米壳
质子纳米粒子的光学特性会因空间组织的不同而发生巨大变化。因此,精确控制其组装结构的能力对于基础理解和实际应用都非常重要。在本文中,我们介绍了一种模板表面活性剂辅助种子生长法,用于合成具有可控表面形态和光学特性的核壳型金纳米粒子组装体。这种方法提供了一种在聚合物模板上同时生长和组装金属纳米粒子的简单程序,可产生定义明确的纳米结构,如尖刺状纳米壳和树莓状元分子,并具有有用而有趣的光学特性,如强而均匀的表面增强拉曼散射和超材料特性。我们讨论了控制形态和集合特性的因素,描述了从该系统中获得的设计规则,并提出了该研究领域的未来发展方向。
