本文研究了长金纳米管的壁厚对光散射特性的影响。结果表明，金壁厚度的变化对光散射有很大的影响，从而导致表面等离子体共振（SPR）特性的变化。理论计算表明，在可见光区有一个光散射峰。此外，随着金壁厚度的增加，该散射峰蓝移并非线性增加。对于金纳米管，有效平均自由程等于管壁弦长，对散射带宽有重要影响。(c)2006 Elsevier B.V.保留所有权利。
In this paper, we investigate the effects of wall thickness on the light scattering characters of long gold nanotubes. The light scattering is shown to be strongly influenced by the changing of the gold wall thickness which leads the changes of surface plasmon resonance (SPR) properties. Theoretical calculations indicated one light scattering peak occurs in visible region. Furthermore, with increasing the gold wall thickness, this scattering peak blue shifts and increases nonlinearly. For gold nanotubes, the effective mean free path equal to the length of wall chord, which plays an important role to influence the scattering bandwidth. (c) 2006 Elsevier B.V. All rights reserved.
