“…Solving this system of equations gives F ZPL ¼ 62 and DW ¼ 0.019 for a measured t bulk B12.5 ns (the average lifetime of NVs in the un-patterned diamond membrane). The DW has been reported in a range from 0.01 to 0.19 at low temperature 2 , and has been shown to vary significantly with temperature shifts 15 ; because of this wide variability, we emphasize that it is important to obtain DW from separate measurements, as this strongly influences the estimated value of F ZPL . From a measured F ZPL of 62, we calculate a beta factor (b) of 0.54 which implies that the NV being enhanced is coupling 450% of its emission into one cavity mode.…”

Coherent spin control of a nanocavity-enhanced qubit in diamond

A central aim of quantum information processing is the efficient entanglement of multiple stationary quantum memories via photons. Among solid-state systems, the nitrogen-vacancy centre in diamond has emerged as an excellent optically addressable memory with second-scale electron spin coherence times. Recently, quantum entanglement and teleportation have been shown between two nitrogen-vacancy memories, but scaling to larger networks requires more efficient spin-photon interfaces such as optical resonators.Here we report such nitrogen-vacancy-nanocavity systems in the strong Purcell regime with optical quality factors approaching 10,000 and electron spin coherence times exceeding 200 ms using a silicon hard-mask fabrication process. This spin-photon interface is integrated with on-chip microwave striplines for coherent spin control, providing an efficient quantum memory for quantum networks.

“…Stark shifts of the excited state cannot be measured optically under ambient conditions due to phonon-induced mixing [30]. However, within each orbital of the molecular doublet, the electric-field-induced splitting of the m I = 0 hyperfine manifold can be detected by optically detectable magnetic resonance (ODMR).…”

High-sensitivity spin-based electrometry with an ensemble of nitrogen-vacancy centers in diamond

We demonstrate a spin-based, all-dielectric electrometer based on an ensemble of nitrogen-vacancy (NV − ) defects in diamond. An applied electric field causes energy-level shifts symmetrically away from the NV − 's degenerate triplet states via the Stark effect; this symmetry provides immunity to temperature fluctuations allowing for shot-noise-limited detection. Using an ensemble of NV − s, we demonstrate shot-noise-limited sensitivities approaching 1 (V/cm)/ √ Hz under ambient conditions, at low frequencies (<10 Hz), and over a large dynamic range (20 dB). A theoretical model for the ensemble of NV − s fits well with measurements of the ground-state electric susceptibility parameter k ⊥ . Implications of spin-based, dielectric sensors for micron-scale electric-field sensing are discussed.

“…The two main techniques of diamond manufacturing are typically used, the high pressure-high temperature (HPHT) and the chemical vapour deposition (CVD). The ideal sensor should contain about 500 NVs [14], hosted in a nanocrystal of ultrapure diamond below 100 nm size. Creation of fluorescent nanodiamonds (fNDs) presents several difficulties since the nanocrystals should be strain-less and defects-free but with high-NV concentration.…”

Nitrogen vacancy color centers in diamond (NVs) as a new type of temperature sensors were presented in the article. Recent progress in the field of NV thermometry and summarize the techniques of NVs manufacturing was briefly discussed. The use of NVs for characterization of thermoelectric materials was proposed. KEYWORDS: nitrogen-vacancy, NV, thermometry, thermoelectrics, nanodiamondsW artykule zaprezentowano centra barwne azot-wakancja (NV) w diamentach w roli czujnika temperatury nowego typu. Krótko omówiono ostatnie doniesienia naukowe oraz podsumowano techniki wytwarzania diamentów z centrami NV. Zaproponowano nowatorskie wykorzystanie centrów NV do badania materiałów termoelektrycznych SŁOWA KLUCZOWE: azot-wakancja, NV, termometria, termoelektryki, nanodiamenty Modern thermometryMany methods have been developed for measuring temperature. Among the most important challenges remaining in the thermometry field are high-sensitivity measurements with a sub-micrometer spatial resolution. The development of precise micro-/nanoscale temperature measurements is important in many research fields [1]. It might be very useful e.g. to track and control intracellular processes in biology/medicine [2], chemical reactions [1] and/or quality of the new materials (e.g. thermoelectrics or semiconductors). These issues motivate a demand for new sensors and drive the progress in the field. Examples of the new developments are scanning thermal microscopes [3], dispersed or scanned fluorescent nanoprobes [4,5], and Raman spectroscopes [6]. Despite many novel techniques, precise nanoscale temperature measurements have not been realized so far. The nitrogen-vacancy (NV) center in diamond is a promising candidate to fill this gap. Diamond with NV center as a temperature sensorDiamond crystals are known for high hardness and chemical inertness. Thanks to the superb thermal conductivity, diamond is also an ideal material to host a temperature sensor. In this paper the nitrogen-vacancy color centers are introduced [7]. These extraordinary objects are used as sensors in different fields, like quantum information processing [8], magnetometry [9], optical tracking [2] and thermometry [1]. The NV center may be incorporated into nanodiamonds (NDs) and serve as a thermometric sensor, which might be localized with a nanometer resolution [1]. Moreover, nanodiamonds are biocompatible and might be introduced and tracked within living cells [2]. The sensing is performed optically in an non-contact and non-destructive way. The sensitivity of such sensors could potentially reach 1 mK [10]. They can be used for temperature measurements up to about 600 K.The NV center consists of a substitutional-nitrogen atom and an adjacent lattice vacancy. The electronic structure of the center contains two triplet levels (spin equal to 1) split by 1.945 eV, which lie within the diamond electronic band gap. The optical excitation of the center with a green light results in a strong and stable red fluorescence [11] (see figure). In room-temperature the ground-stat...
