用电子能量损失谱(EELS)表征了金衬底上并排排列的金纳米棒阵列的表面等离子激元模式。阵列内的等离子体耦合将纳米棒的纵模分裂为亮模式(对称排列的偶极)和暗模式(反对称排列的偶极)。我们通过有限元模型支持这一观察结果。
The surface plasmonic modes of a side-by-side aligned gold nanorod array supported on a gold substrate has been characterised by electron energy loss spectroscopy (EELS). Plasmonic coupling within the array splits the nanorods' longitudinal mode into a bright mode (symmetrically aligned dipoles) and a dark mode (anti-symmetrically aligned dipoles). We support this observation by means of finite element modelling (FEM).
