纳米颗粒的形状敏感拉曼散射

Shape sensitive Raman scattering from Nano-particles

S. P. Apell, G. Mukhopadhyay, Tomasz Antosiewicz, J Aizpurua

摘要:

我们调查的相互作用的形状变化和局部表面等离子体在小的金属颗粒与潜在的一个大的增强拉曼信号从粒子自身的振动。该框架是一个几何的,我们研究的振动运动过程中的几何因素的变化。所得到的横截面被发现是一个可检测的数量级,但远小于弹性横截面。

英文摘要:

We investigate the interplay of shape changes and localized surface plasmons in small metal particles with the potential of a large enhancement of the Raman signal from the particles own vibrations. The framework is a geometrical one where we study the change in geometric factors during the vibrational movement. The resulting cross-section is found to be of a detectable order of magnitude however much smaller than the elastic cross-section.
