Ultrahigh nitrogen-vacancy center concentration in diamond

Carbon, 2022
High concentration of negatively charged nitrogen-vacancy (NV−) centers was created in diamond single crystals containing approximately 100 ppm nitrogen using electron and neutron irradiation and subsequent thermal annealing in a stepwise manner ...

A flexible nitrogen-vacancy center probe for scanning magnetometry

Review of Scientific Instruments, 2021
The key component of the scanning magnetometry based on nitrogen-vacancy centers is the diamond probe. Here, we designed and fabricated a new type of probe with an array of pillars on a (100 µm)2 × 50 µm diamond chip. The probe features high yield, convertibility to be a single pillar, and expedient reusability.

Local Detection of Nitrogen-Vacancy Centers in a Nanodiamond Monolayer

Nano Letters, 2013
Nitrogen-vacancy defect centers (NV) contained in nanodiamonds (NDs) are a promising candidate in quantum information processing and single photon sources due to the capability of controlling their assembly on various surfaces. However, their detection with traditional optical techniques becomes challenging when probing high NV densities at the ...

Photoluminescence studies of nitrogen-vacancy and silicon-vacancy centers transformation in CVD diamond

Journal of Physics: Condensed Matter, 2020
Abstract In this study, the low-temperature micro-photoluminescence (PL) technology was employed to investigate the transformation of nitrogen-vacancy (NV), silicon-vacancy (SiV) centers in diamond crystal. Results showed that the NV and SiV luminescence were controlled by electron irradiation followed by thermal annealing.
