摘要

摘要研究了具有 NV（-）中心的合成金刚石微晶的电子顺磁共振（EPR）光谱。研究表明，在低温 ~100 K 的条件下，用氙灯辐照材料时，与 "禁止"（Δms = 2）和低场允许（Δms = 1）跃迁相对应的 EPR 信号强度会放大数倍，而电荷态-1 的顺磁氮和杂质镍的 EPR 信号实际上没有变化。这是由于 NV（-）-中心的地面三重态的水平群和三重水平 ms = 0 状态下的自旋光学极化发生了变化。

Electron Spin Resonance of NV(–)-Centers in Synthetic Fluorescent Diamond Microcrystals under Conditions of Optical Spin Polarization

Abstract

Electron paramagnetic resonance (EPR) spectra of synthetic diamond microcrystals with NV^(‒)‑centers have been studied. It is shown that under the conditions of irradiation of the material with the light of a xenon lamp at low temperatures ~100 K, the intensities of the EPR signals corresponding to the “forbidden” (Δm_s = 2) and low field allowed (Δm_s = 1) transitions are amplified several times, while the EPR signals from paramagnetic nitrogen and impurity nickel in the charge state –1 practically do not change. This is due to a change in the population of levels of the ground triplet state of the NV^(–)-center and the optical polarization of spins in the state m_s = 0 of the triplet level.
