Pairs of gold nanodisks 40 or 70 nm in diameter were fabricated in silica by electron-beam lithography. On irradiation by 110 MeV Br(10+) ions, the nanodisks elongated to form nanorods; elongation occurred in the direction of propagation of the ions. The aspect ratios of the Au nanorods increased with increasing ion-flux density or fluence and with decreasing diameter of the nanodisks. The elongation mechanism can be explained in terms of a thermal spike model.
通过电子束光刻在二氧化硅中制备了直径为40或70纳米的成对金纳米盘。在110兆电子伏特的溴（10 +）离子辐照下，纳米盘伸长形成纳米棒；伸长发生在离子传播方向上。金纳米棒的纵横比随着离子通量密度或注量的增加以及纳米盘直径的减小而增加。伸长机制可以用热尖峰模型来解释。
