中文摘要：

以金纳米棒为核的核壳结构纳米粒子由于它独特的光学性质、结构特点以及在催化、表面增强拉曼散射方面的应用前景,成为目前纳米材料研究的热点之一。本文重点介绍以金纳米棒为核,包覆其他无机材料的核/壳结构之合成方法,同时阐述其结构特征、光学性质以及外界条件对结构和性质的影响。其中,由于金银纳米核壳结构的研究开始最早,研究最为深入,故对其进行重点阐述。最后对以金纳米棒为核的核壳结构未来研究进行了展望。

英文摘要：

The unique physicochemical properties of gold nanorods make them very useful in the fields of catalytic reactions,ultrasensitive detection,biological diagnostics,and so on.These properties of the gold nanorods can be tailored by either the morphology controlling or the surface coating.The preparation,characterization and optical properties of inorganics-coated gold nanorods that are typically core-shell nanorods are summarized in this paper.The emphasis is focused on the Au@Ag core-shell nanorods that have been widely explored in terms of optical properties and potential applications.Finally,the prospective of the gold-based core-shell nanorods is given.
