金纳米棒二聚体等离子体标尺:利用二阶共振
Plasmon ruler with gold nanorod dimers: utilizing the second-order resonance
摘要:
介绍了利用金纳米棒π-二聚体的二阶等离子体共振作为等离子体标尺的思想。我们报告一个质的不同的依赖性的等离子体共振位移粒子间的距离为第一和第二阶的纵向模式,扩展等离子体统治者的工作范围的距离值为400 nm。
英文摘要:
The idea of utilizing the second-order plasmon resonance of the gold nanorod π-dimers for plasmon rulers is introduced. We report on a qualitatively different dependence of the plasmon resonance shift on the interparticle distance for the first- and second-order longitudinal modes, extending the working range of plasmon rulers up to the distance values of 400 nm.
