“…For Figure 6 a, the slope of the dose dependence of the

rate was 0.16, which is twice as large as for the

dependence shown in Figure 6 b, where the slope was 0.08. These results appear to be consistent with the earlier observations [ 26 , 36 , 37 , 38 , 39 ] where the role of dipolar interaction in dense samples was identified. In Ref.…”

We present an experimental study of the longitudinal and transverse relaxation of ensembles of negatively charged nitrogen-vacancy (NV−) centers in a diamond monocrystal prepared by 1.8 MeV proton implantation. The focused proton beam was used to introduce vacancies at a 20 µµm depth layer. Applied doses were in the range of 1.5×1013 to 1.5×1017 ions/cm2. The samples were subsequently annealed in vacuum which resulted in a migration of vacancies and their association with the nitrogen present in the diamond matrix. The proton implantation technique proved versatile to control production of nitrogen-vacancy color centers in thin films.

“…The spatially controlled preparation of diamonds with color centers is of particular interest. 10 Group IV vacancy defect centers (silicon, SiV, 32−36 and germanium, GeV 37−39 ) seem to be very promising as well. As was predicted in a work by Goss, 40 they have similar photostability and spectral broadening but are different with respect to some other properties.…”

Diamonds with impurity color centers are a novel class of functional materials with potential for various photonics applications such as quantum optics, metrology, sensorics, and life sciences. When introducing defect centers, a broad range of questions arises about the nature of the photophysical processes in the new materials, in particular regarding the relationship between spectral and morphological properties. Here we present results of comprehensive spectroscopic studies on diamond films with germanium-vacancy (GeV–) centers, synthesized by chemical vapor deposition from gaseous germane (GeH4). The combination of different techniques (emission and fluorescence excitation spectroscopy, epi-microscopy, and nanoscopy up to the single-emitter level) at room and cryogenic temperatures has shed light onto the spatial distribution of the spectral properties of the GeV– centers in different microregions of the diamond crystal and its relation to local strain/stress. We demonstrate a clear correlation between inhomogeneous broadening and morphological heterogeneities of the sample. Ultranarrow (tens of MHz) stable zero-phonon lines have been observed, which are a prerequisite for various applications.

“…Apart from the incorporation of nitrogen impurities, another important aspect is to create lattice vacancies in diamond for the formation of NV centers. To date, the introduction of vacancies in diamond is mainly achieved by irradiation with ions, − protons, , α particles generated isotropically by 10 B neutron capture, electrons, , and laser techniques . Selection of the NV creation technique largely depends on the intended application, for example, whether the aim is to create single NV defects or their ensembles …”

Toward Quantitative Bio-sensing with Nitrogen–Vacancy Center in Diamond

et al. 2021

View full text Add to dashboard Cite

The long-dreamed-of capability of monitoring the molecular machinery in living systems has not been realized yet, mainly due to the technical limitations of current sensing technologies. However, recently emerging quantum sensors are showing great promise for molecular detection and imaging. One of such sensing qubits is the nitrogen−vacancy (NV) center, a photoluminescent impurity in a diamond lattice with unique roomtemperature optical and spin properties. This atomic-sized quantum emitter has the ability to quantitatively measure nanoscale electromagnetic fields via optical means at ambient conditions. Moreover, the unlimited photostability of NV centers, combined with the excellent diamond biocompatibility and the possibility of diamond nanoparticles internalization into the living cells, makes NV-based sensors one of the most promising and versatile platforms for various life-science applications. In this review, we will summarize the latest developments of NV-based quantum sensing with a focus on biomedical applications, including measurements of magnetic biomaterials, intracellular temperature, localized physiological species, action potentials, and electronic and nuclear spins. We will also outline the main unresolved challenges and provide future perspectives of many promising aspects of NV-based bio-sensing.
