摘　　要：近二十年来,贵金属纳米颗粒由于其独特的性质,已成为人们广泛研究的课题.研究人员应用多种方法来合成纳米尺度的贵金属材料并且探讨了纳米材料的性质与尺寸和形状的关系.本文简单回顾贵金属纳米颗粒的合成方法,主要讨论纳米颗粒的形状对其光学性质的影响和颗粒的生长机制,最后简述贵金属纳米材料的应用前景.In the past two decades, noble metal nanoparticles have been the focus of intensive research due to their unique properties. Researchers have made many efforts to synthesize noble metals with sizes in the nanometer scale and investigated their size- and shape-dependent properties. In this article, we firstly give a brief review on recent synthesis of noble metal particles. Then we mainly discuss their growth mechanism and the relationship between the shape and optical properties. Finally, we highlight a number of potential applications of noble metal materials in some fields.
