我们提出了使用金刚石中植入的单氮空位（NV）中心阵列进行高灵敏度温度检测。在静磁场中对金刚石中植入的单个 NV 中心进行了高阶热 Carr-Purcell-Meiboom-Gill (TCPMG) 方法。我们证明，在两个驱动微波频率的小失谐下，NV中心的诱导荧光的振荡频率大约等于两个驱动场失谐的平均值。根据该结论，可以确定NV中心的零场分裂D和相应的温度。实验表明，高阶TCPMG的相干时间得到了有效延长，特别是TCPMG-8的相干时间延长至108μs，约为热Ramsey方法7.7μs的14倍。该相干时间对应于 10.1 mK/Hz(1/2) 的热灵敏度。我们还通过 TCPMG-3 方法使用植入式 NV 中心阵列检测了三种不同情况下金刚石芯片表面的温度分布。该实验表明，利用高品质钻石中植入的 NV 中心以高灵敏度和纳米级分辨率检测生物学、化学、材料科学和微电子系统中的温度是可行的。
We presented a high-sensitivity temperature detection using an implanted single nitrogen-vacancy (NV) center array in diamond. The high-order thermal Carr-Purcell-Meiboom-Gill (TCPMG) method was performed on the implanted single NV center in diamond in a static magnetic field. We demonstrated that under small detunings for the two driving microwave frequencies, the oscillation frequency of the induced fluorescence of the NV center equals approximately the average of the detunings of the two driving fields. On the basis of the conclusion, the zero-field splitting D for the NV center and the corresponding temperature could be determined. The experiment showed that the coherence time for the high-order TCPMG was effectively extended, particularly up to 108 mu s for TCPMG-8, about 14 times the value 7.7 mu s for thermal Ramsey method. This coherence time corresponded to a thermal sensitivity of 10.1 mK/Hz(1/2). We also detected the temperature distribution on the surface of a diamond chip in three different circumstances by using the implanted NV center array with the TCPMG-3 method. The experiment implies the feasibility of using implanted NV centers in high-quality diamonds to detect temperatures in biology, chemistry, materials science, and microelectronic systems with high sensitivity and nanoscale resolution.
