We report on the experimental and theoretical study of the spatial fluctuations of the local density of states (EM-LDOS) and of the fluorescence intensity in the near-field of a gold nanoantenna. EM-LDOS, fluorescence intensity and topography maps are acquired simultaneously by scanning a fluorescent nanosource grafted on the tip of an atomic force microscope at the surface of the sample. The results are in good quantitative agreement with numerical simulations. This work paves the way for a full near-field characterization of an optical nanoantenna.
我们报告了关于金纳米天线近场中局域态密度（EM-LDOS）的空间涨落以及荧光强度的实验和理论研究。通过在样品表面扫描接枝在原子力显微镜尖端的荧光纳米源，同时获取EM-LDOS、荧光强度和形貌图。结果与数值模拟在定量上吻合良好。这项工作为光学纳米天线的全近场表征铺平了道路。
