贵金属纳米线因独特的光学性质吸引了人们的普遍关注，已经被广泛应用于生物传感器、太阳能电池、纳米尺度光电器件领域。其光学性能主要来源于贵金属表面的区域等离子体共振，而区域等离子体共振主要由金属纳米线的形状、尺寸、组成以及电磁常数决定。简要地回顾了模板法合成贵金属纳米线的方法，讨论了影响纳米线光学性质的因素，最后简述了应用前景。
Optical properties of noble metal nanowires have drawn particular interest due to their significant ap-plications in nanoscale research,such as biosensors,solar cells,and optoelectronic devices.The unique optical proper-ties of noble nanowires primarily originate from the localized surface plasmon resonance,which depends on the size, shape,composition,and dielectric character of the nanowires.In this article,we firstly give a brief review on synthe-sis of noble metal nanowires,then mainly discuss the relationship between their shape and optical properties.Finally, a number of potential applications of noble metal materials are introduced.
