目前的远场光学纳米方案通过确保相邻特征在检测时呈现不同的状态来克服Me衍射屏障。理想情况下，这些状态之间的转换可以无限重复，如果用光学方法进行，则需要低水平的光。在这里，我们报告这样的光学开关，实现了配对的发光三重态和长寿命的黑暗状态的钻石色心，使他们的成像分辨率超过10倍的衍射障碍（
Current far-field optical nanoscopy schemes overcome Me diffraction barrier by ensuring that adjacent features assume different states upon detection. Ideally, the transition between these states can be repeated endlessly and, if performed optically, with low levels of light. Here we report such optical switching, realized by pairing the luminescent triplet and a long-lived dark state of diamond color centers, enabling their imaging with a resolution > 10 times beyond the diffraction barrier (
