We presented a high-sensitivity temperature detection using an implanted single Nitrogen-Vacancy center array in diamond. The high-order Thermal Carr-Purcell-Meiboom-Gill (TCPMG) method was performed on the implanted single nitrogen vacancy (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 to the average of the detunings of the two driving fields. On 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 µs for TCPMG-8, about 14 times of the value 7.7 µs 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 for using implanted NV centers in high-quality diamonds to detect temperatures in biology, chemistry, material science and microelectronic system with high-sensitivity and nanoscale resolution.In recent years some thermal detection techniques have been developed to map temperature distribution with spatial resolution down to micrometer-nanometer range The NV center is a spin defect consisting of a substitutional nitrogen impurity adjacent to a carbon vacancy in diamond. It has increasingly attracted attention in recent years owing to its excellent properties, like photostability, biocompatibility, chemical inertness, and long spin coherence and relaxation times (∼ms in the isotopically pure diamond) at room temperature. These remarkable properties have been explored in many applications like quantum information processing, [12][13][14][15][16] metrologies such as magnetic field sensing, [17][18][19] electric field sensing, [20,21] force sensing, [22,23] thermal sensing, [8][9][10] single electron and nuclear spin sensing, [24][25][26] and external nuclear spin sensing. [27,28] In thermal sensing, Neumann et al. demonstrated the measurement of the temperature distribution on a glass coverslip using single NV center nanodiamonds as temperature sensors.[9] However, the thermal sensitivity was unsatisfactory due to the short coherence time. To address the short coherence time issue, Toyli et al. proposed the thermal Carr-Purcell-Meiboom-Gill (TCPMG) method and extended the spin coherence time up to 17 µs by TCPMG-2. [8] For further increasing the spin coherence time for the thermometry, in this work, we firstly studied the effects of the higher order TCPMG method applied on the implanted single NV centers in diamond at room temperature. In particular, a coherence time of 108 µs was obtained for TCPMG-8, about 14 times of the value 7.7 µs for Thermal Ramsey (T-Ramsey) method. This value corr...
