Red-shift effect on the zero field splitting for negatively charged nitrogen-vacancy centers in diamond
Wang Zheng, Zhang Jintao, Feng Xiaojuan +1
The zero field splitting (ZFS) quantifies the energy difference for the ground electron spin-triplet of a nitrogen-vacancy center in the absence of external fields. The values of t…
Temperature sensing using nitrogen-vacancy centers with multiple-poly crystal directions based on Zeeman splitting
Li Xing, Xiaojuan Feng, Jintao Zhang +1
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) cente…
