纳米三角银制备方法概述

Preparation Methods of Triangular Silver Nanoplates

纳米三角银由于其结构的特异性使其具有特殊的表面等离子体共振性能,其在光学传感器、生物传感器、化学传感器、表面增强拉曼光谱等领域具有广阔的应用前景。介绍了纳米三角银的表面等离子体共振性能,三种主要制备方法:纳米球平板印刷法、光诱导法和热还原法,以及在使用热还原法制备纳米三角银时各反应物所起到的作用。

Due to its special surface plasmon resonance property, triangular silver nanoplates have wide applications in optical sensors,biosensors,chemical sensors and surface-enhanced Raman spectrum. In this paper, the special surface plasmon resonance property of triangular silver nanoplates was introduced. Three main preparation methods, including nanosphere lithography method, photoinduced method and thermal reduction method, were reviewed. In addition, effects of each reagents on the morphologies of triangular silver nanoplates obtained by thermal reduction method were also systematically discussed.
