Diamond中的氮 - 颜色中心是快速增长的传感领域中最重要的系统之一。该颜色中心都用于高分辨率和高敏感性传感器中。但是，该颜色中心快速有效地层的技术仍处于开发阶段。在本文中，我们介绍了一项关于电子辐照剂量对替代氮转化为$ \ text {n} {\ text {v}^{ - }} $中心的影响的研究。这项研究是在高度富含氮（约100 ppm）的钻石上进行的，该钻石一方面应最大程度地发挥辐射的作用，而另一方面，对于高敏感性磁力计而感兴趣。达到的最大转化效率高达$ {37 \ pm 3.7} $，即使使用最简单的退火过程，电子剂量也没有观察到的饱和度。相应的发定时间的测量结果使得可以估算出射击量有限的固定场传感器的敏感性有限的敏感性，具有这样的钻石为$ {9 \ pm 1 \ pm 1 \ times {{10}^{ - 14}} { - 14}}} \ text {t}}}}}}}}}}}/{\ sqrt {\ sqrt {\ sqrt { \ text {m} {\ text {m}^{ - 3}}}}}} \; $。
The nitrogen-vacancy color center in diamond is one of the most important systems in the fast-growing field of sensing. This color centers are used in both high-resolution and high-sensitivity sensors. However, techniques for quick and efficient formations of this color center are still in the development stage. In this paper, we present a study on the influence of the electron irradiation dose on the conversion of substitutional nitrogen into $\text{N}{\text{V}^{-}}$ centers. The study was done on diamonds that were highly enriched with nitrogen (~100 ppm), which on one hand should maximize the effect of irradiation, and on another be of interest for high-sensitivity magnetometers. The maximum achieved conversion efficiency was as high as ${37\pm 3.7}$, with no observed saturation on the electron dose even with the simplest annealing procedure. The measurements of the corresponding dephasing time made it possible to estimate for shot-noise limited sensitivity per unit volume of a stationary field sensor with such a diamond to be ${9\pm 1\times {{10}^{-14}}\text{T}}/{\sqrt{\text{Hz}\cdot \text{m}{\text{m}^{-3}}}}\;$.
