Abstract

The magnetic sensitivity of the ensemble NV centers is directly related to temperature. In this study, we systematically investigated the temperature dependence of photoluminescence properties and optical detection magnetic resonance in ensemble NV centers from 1.6 K to 300 K. The magnetic sensitivity of the ensemble NV centers increases with the temperature rising in the range of 1.6 K to 75 K due to changes in contrast and linewidth, reaching a minimum near 40 K. Furthermore, the decrease in sensitivity is attributed to laser intensity overload at low temperatures by studying the influence of laser power on contrast and linewidth. These results offer valuable insights into NV magnetic sensing applications.

集合 NV 中心磁灵敏度的温度依赖性

集合 NV 中心的磁灵敏度与温度直接相关。在这项研究中，我们系统地研究了 1.6 K 至 300 K 范围内集合 NV 中心的光致发光特性和光探测磁共振的温度依赖性。在 1.6 K 至 75 K 范围内，由于对比度和线宽的变化，集合 NV 中心的磁灵敏度随着温度的升高而增加，在 40 K 附近达到最小值。此外，通过研究激光功率对对比度和线宽的影响，还发现灵敏度的降低是由于激光强度在低温下过载造成的。这些结果为近紫外磁感应应用提供了宝贵的见解。
