论文摘要
我们研究了在矩形阵列中排列的纳米颗粒的集体效应如何影响其时间等离子体响应和现场增强特性。通过系统地更改包含相同金属纳米棒的阵列的晶格常数，我们在实验上证明了光栅诱导的效应如何影响位置，更重要的是，灭绝光谱的扩大。我们将这些效应与可实现的场增强和等离子体瞬变的时间持续时间相关联，并制定了增强的几个周期局部等离子体振荡的标准。
We study how the collective effects of nanoparticles arranged in rectangular arrays influence their temporal plasmon response and field enhancement property. By systematically changing the lattice constant for arrays containing identical metal nanorods, we experimentally demonstrate how grating induced effects affect the position and, more importantly, the broadening of extinction spectra. We correlate these effects with the achievable field enhancement and the temporal duration of plasmon transients and formulate criteria for the generation of enhanced few-cycle localized plasmon oscillations.
