我们报道了通过多晶化学气相沉积膜的珠辅助声波崩解（BASD）生产70-80纳米尺寸的纳米金刚石（NDs）。高晶体质量的NDs在738 nm处显示出强烈的窄带（7 nm）室温发光，来自原位硅空位中心。我们展示了明亮的窄带单光子发射，速度为bbb10 100,000 cps。由于较窄的荧光带宽和近红外发射，这些nd也适合作为荧光标记，显著增强了在体内成像的性能。
We report on the production of nanodiamonds (NDs) with 70–80 nm size via bead assisted sonic disintegration (BASD) of a polycrystalline chemical vapor deposition film. The high crystalline quality NDs display intense narrowband (7 nm) room temperature luminescence at 738 nm from in situ incorporated silicon vacancy centers. We demonstrate bright, narrowband single photon emission with >100 000 cps. Due to the narrow fluorescence bandwidth as well as the near-infrared emission these NDs are also suitable as fluorescence labels with significantly enhanced performance for in vivo imaging.
