We present a scanning-probe microscope based on an atomic-size emitter, a single nitrogen-vacancy center in a nanodiamond. We employ this tool to quantitatively map the near-field coupling between the NV center and a flake of graphene in three dimensions with nanoscale resolution. Further we demonstrate universal energy transfer distance scaling between a point-like atomic emitter and a two-dimensional acceptor. Our study paves the way toward a versatile single emitter scanning microscope, which could image and excite molecular-scale light fields in photonic nanostructures or single fluorescent molecules.
我们提出了一种基于原子尺寸发射器的扫描探针显微镜，该发射器是一个纳米金刚石中的单个氮空位中心。我们使用这个工具以纳米级分辨率在三维空间中定量地绘制了 NV 中心和石墨烯薄片之间的近场耦合。此外，我们还证明了点式原子发射器和二维受体之间的通用能量转移距离标度关系。我们的研究为多功能单发射器扫描显微镜铺平了道路，这种显微镜可以在光子纳米结构或单个荧光分子中成像和激发分子尺度的光场。
