表面等离激元金属纳米粒子的多元化结构及应用

Multiplex Structures of Plasmonic Metal Nanoparticles and Their Applications

目前,单一的金属纳米粒子结构已经难以满足多学科交叉发展的需求.因此,将多种金属纳米粒子(如不同尺寸、形状、组分等)集成在同一基底表面,能够充分发挥不同金属纳米粒子的性质和优势,极具研究价值和应用价值.本文介绍了多元化表面等离激元纳米粒子结构的构筑方法,以及其在信息编码、光电器件、能源催化等领域的应用.最后,提出了当前在多元化结构制备中存在的挑战,并展望了利用多元化结构实现性能提升的前景.

Currently,metal nanoparticle structure with single structural design or component has been difficult to meet the requirements of interdisciplinary development.Therefore,the integration of multiplex metal nanoparticles(such as different sizes,shapes,components or spacing)onto one substrate can fully show the properties and advantages coming from different metal nanoparticles simultaneously,which have significant research and application value.This review introduces the methods of fabricating multiplex plasmonic nanoparticle structures,as well as their potential applications in surface encoding,optoelectronic devices and photocatalysis.Finally,we put forward the challenges in the structural construction and the prospects in the performance improvement using multiplex structures.
