标题： Single Defect Centers in Diamond Nanocrystals as Quantum Probes for Plasmonic Nanostructures

摘要： 我们展示了单个氮空位中心在纳米金刚石中作为等离子体纳米结构的量子探针的两个应用。通过使用原子力显微镜拾取一个预先表征的纳米晶体并将其放置在所需位置，实现了与纳米结构的高度受控耦合。展示了通过几纳米的空间控制将单个激发态局部注入纳米线。此外，得到了等离子体梳形天线电磁环境的二维图谱，类似于荧光寿命显微镜的极限。 显示英文摘要

摘要： We present two applications of a single nitrogen vacancy center in a nanodiamond as quantum probe for plasmonic nanostructures. Coupling to the nanostructures is achieved in a highly controlled manner by picking up a pre-characterized nanocrystal with an atomic force microscope and placing it at the desired position. Local launching of single excitations into a nanowire with a spatial control of few nanometers is demonstrated. Further, a two dimensional map of the electromagnetic environment of a plasmonic bowtie antenna was derived, resembling an ultimate limit of fluorescence lifetime nanoscopy.
