Quantum emitters in two-dimensional hexagonal boron nitride (hBN) are attractive for a variety of quantum and photonic technologies because they combine ultra-bright, room-temperature single-photon emission with an atomically thin crystal. However, the emitter’s prominence is hindered by large, strain-induced wavelength shifts. We report the discovery of a visible-wavelength, single-photon emitter (SPE) in a zero-dimensional boron nitride allotrope (the boron nitride nanococoon, BNNC) that retains the excellent optical characteristics of few-layer hBN while possessing an emission line variation that is lower by a factor of 5 than the hBN emitter. We determined the emission source to be the nanometer-size BNNC through the cross-correlation of optical confocal microscopy with high-resolution scanning and transmission electron microscopy. Altogether, this discovery enlivens color centers in BN materials and, because of the BN nanococoon’s size, opens new and exciting opportunities in nanophotonics, quantum information, biological imaging, and nanoscale sensing.

氮化硼纳米茧中的单光子发射极

二维六方氮化硼（hBN）中的量子发射器对于多种量子和光子技术都具有吸引力，因为它们将超亮的室温单光子发射与原子上薄的晶体结合在一起。但是，由于应变引起的大的波长偏移会阻碍发射器的突出。我们报道了在零维氮化硼同素异形体（氮化硼纳米茧，BNNC）中发现可见光，单光子发射体（SPE）的发现，该结构保留了几层hBN的出色光学特性，同时具有发射线变化比hBN发射器低5倍。通过光学共聚焦显微镜与高分辨率扫描和透射电子显微镜的互相关，我们将发射源确定为纳米级BNNC。共，
