摘要:

金刚石中的氮空位中心(NV中心)在对应于基态能级反交叉(GSLAC)区域的磁场中由于电子自旋态之间的能隙消失而产生丰富的光致发光(PL)信号,这使得能够对NV中心的发光产生广泛的各种环境耦合的影响。在这篇文章中,我们报告的GSLAC光致发光签名的NV系综在不同的自旋环境中,在各种外场。我们研究了横向电场和磁场,P1中心,NV中心,和$^{13}$ C核自旋的影响,其中每一个都产生了一个独特的PL签名在GSLAC。在GSLAC的耦合和相关的光信号的综合分析提供了一个坚实的基础,在GSLAC推进各种微波的应用,包括但不限于磁力,光谱,动态核极化(DNP),和核磁共振(NMR)检测。我们证明,不仅是最丰富的$^{14}$ NV中心,但$^{15}$ NV也可以在这样的应用程序中使用,并耦合到P1中心的核自旋可以直接极化的NV中心在GSLAC,通过一个巨大的有效的核$g$因子所产生的NV中心P1中心核自旋耦合。我们报告的新的替代测量缺陷浓度在附近的NV中心和相互作用,相互对齐的NV中心的光学签名。

英文摘要:

The nitrogen-vacancy center (NV center) in diamond at magnetic fields corresponding to the ground state level anticrossing (GSLAC) region gives rise to rich photoluminescence (PL) signals due to the vanishing energy gap between the electron spin states, which enables to have an effect on the NV center's luminescence for a broad variety of environmental couplings. In this article we report on the GSLAC photoluminescence signature of NV ensembles in different spin environments at various external fields. We investigate the effects of transverse electric and magnetic fields, P1 centers, NV centers, and the $^{13}$C nuclear spins, each of which gives rise to a unique PL signature at the GSLAC. The comprehensive analysis of the couplings and related optical signal at the GSLAC provides a solid ground for advancing various microwave-free applications at the GSLAC, including but not limited to magnetometry, spectroscopy, dynamic nuclear polarization (DNP), and nuclear magnetic resonance (NMR) detection. We demonstrate that not only the most abundant $^{14}$NV center but the $^{15}$NV can also be utilized in such applications and that nuclear spins coupled to P1 centers can be polarized directly by the NV center at the GSLAC, through a giant effective nuclear $g$-factor arising from the NV center-P1 center-nuclear spin coupling. We report on new alternative for measuring defect concentration in the vicinity of NV centers and on the optical signatures of interacting, mutually aligned NV centers.
