摘要
基于金刚石系综氮空位(NV)色心量子传感技术,搭建了高精度量子传感温度测量实验平台,探究了金刚石NV色心温度传感特性。通过测试不同温度下的光探测磁共振(ODMR)信号,验证了NV色心的零场劈裂参数(D)会随着温度(T)变化这一结论,即随着温度的升高,ODMR信号整体往左漂移。测得在293~343 K内,D与T呈线性关系,且斜率为-62.4 kHz/K。本实验不仅为高灵敏度和高空间分辨率的纳米尺度温度场测量提供了方法,也对NV色心温度传感器的设计和NV色心量子精密测量提供了技术支持。
Based on the diamond ensemble nitrogen vacancy(NV)color center quantum sensing technology,a high-precision quantum sensing temperature measurement experimental platform was built to explore the temperature sensing characteristics of the diamond NV color center.By testing optical detection magnetic resonance(ODMR)signals at different temperatures,the conclusion that the zero-field splitting parameter(D)of the NV color center changes with the temperature(T)is verified,that is,with the increase of temperature,the whole ODMR signal drifts to left.And it is measured that in the temperature range of 293-343 K,D has a linear relationship with T and the slope is-62.4 kHz/K.The experiment provides a method for the nano-scale temperature field measurement with high-sensitivity and high-spatial resolution,and provides a technical support for the design of the NV color center temperature sensor and the precision measurement of the NV color center quantum.
