摘要

自由电子与电磁场的耦合接近但低于限制金属纳米结构的等离子体频率导致等离子体共振。它们的光谱响应强烈依赖于几何形状，即，对于纳米棒来说，截面与长度的长宽比的变化会改变共振频率。这样，等离子共振可以从蓝色调谐到红外线，但不是主动的。

Fast Electrical Modulation of Single Plasmonic Nano-Rod Resonance

Coupling of free electrons with electromagnetic fields near but below the plasma frequency of confined metallic nanostructures leads to plasmonic resonances. Their spectral response is strongly dependent on the geometry, i.e., for nanorods, changes in the aspect ratio of the cross-section to the length shift the resonance frequency. In this way, plasmonic resonances can be tuned from blue to infrared, but not actively.
