我们介绍了一个点状扫描单光子源，在室温下工作，并提供了一个特殊的光稳定性（无闪烁，无漂白）。这是通过以受控的方式在光学探针的顶点处接枝具有单个氮空位色心占据的金刚石纳米晶（尺寸约20 nm）来获得的。作为一个应用，我们在近场成像金属纳米结构，从而实现了近场扫描单光子显微镜在室温下的长期工作。我们的工作可能是重要的纳米科学的各种新兴领域，其中需要一个精确的定位的量子发射器，例如量子等离子体。(C)2009年美国光学学会
We introduce a point-like scanning single-photon source that operates at room temperature and offers an exceptional photostability (no blinking, no bleaching). This is obtained by grafting in a controlled way a diamond nanocrystal (size around 20 nm) with single nitrogen-vacancy color-center occupancy at the apex of an optical probe. As an application, we image metallic nanostructures in the near-field, thereby achieving a near-field scanning single-photon microscopy working at room temperature on the long term. Our work may be of importance to various emerging fields of nanoscience where an accurate positioning of a quantum emitter is required such as for example quantum plasmonics.
