由于氮空位缺陷中心存在于金刚石晶格中，具有广泛的应用前景，近年来人们对金刚石进行了广泛的研究。其应用包括磁强计和量子信息技术，而NV中心的长退相干时间对这些应用至关重要。虽然人们已经知道顺磁性杂质在金刚石中的浓度很大程度上取决于顺磁性杂质的浓度，但杂质浓度的精确测量仍然具有挑战性。在本工作中，我们展示了一种利用宽带高频电子自旋共振和双电子-电子共振谱仪测定金刚石中氮浓度的方法。此外，我们还研究了氮杂质，并指出了两者之间的关系。该方法适用于固体中的各种自旋系统，并可在具有NV中心的纳米级磁共振波谱中实现，以表征微观体积内顺磁自旋的浓度。
Diamond has been extensively investigated recently due to a wide range of potential applications of nitrogen-vacancy (NV) defect centers existing in a diamond lattice. The applications include magnetometry and quantum information technologies, and long decoherence timeof NV centers is critical for those applications. Although it has been known thathighly depends on the concentration of paramagnetic impurities in diamond, precise measurement of the impurity concentration remains challenging. In the present work we show a method to determine a wide range of the nitrogen concentrationin diamond using a wide-band high-frequency electron spin resonance and double electron-electron resonance spectrometer. Moreover, we investigateof the nitrogen impurities and show the relationship betweenand. The method developed here is applicable for various spin systems in solid and implementable in nanoscale magnetic resonance spectroscopy with NV centers to characterize the concentration of the paramagnetic spins within a microscopic volume.
