Abstract

We demonstrate a novel method based on the Zeeman splitting of electronic spins to improve the performance for temperature sensing of negatively-charged nitrogen-vacancy (NV) centers in multiple-poly diamond. The theoretical model for selection principle of resonance peaks corresponding to a single NV axis for determining the temperature dependence is clarified. The spectral linewidth is effectively narrowed and the thermometer is insensitive to magnetic field fluctuations. Repeatability and accuracy of the relationship calibration between the zero-field splitting (ZFS) parameter D and temperature T in the range of 298 K to 323 K is significantly improved, and the results of coefficient dD/dT is 75.33 kHz/K. Finally, this method promotes the average temperature measurement sensitivity (below 10 Hz) of our setup from 0.49 K/Hz1/2 to 0.22 K/Hz1/2.
