NV-centers in Nanodiamonds: How good they are [PDF]
Diamond and Related Materials, 2017 This paper presents a method for determination of the size distribution for diamond nanocrystals containing luminescent nitrogen-vacancy (NV) centers using the luminescence intensity only.

Controlled Surface Modification to Revive Shallow NV- Centers. [PDF]
Nano Lett, 2023 Near-surface negatively charged nitrogen vacancy (NV) centers hold excellent promise for nanoscale magnetic imaging and quantum sensing. However, they often experience charge-state instabilities, leading to strongly reduced fluorescence and NV coherence time, which negatively impact magnetic imaging sensitivity.

Relaxometry with Nitrogen Vacancy (NV) Centers in Diamond. [PDF]
Acc Chem Res, 2022 Relaxometry is a technique which makes use of a specific crystal lattice defect in diamond, the so-called NV center. This defect consists of a nitrogen atom, which replaces a carbon atom in the diamond lattice, and an adjacent vacancy. NV centers allow converting magnetic noise into optical signals, which dramatically increases the sensitivity of the ...

Photonic Quantum Networks formed from NV(-) centers. [PDF]
Sci Rep, 2016 AbstractIn this article we present a simple repeater scheme based on the negatively-charged nitrogen vacancy centre in diamond. Each repeater node is built from modules comprising an optical cavity containing a single NV−, with one nuclear spin from 15N as quantum memory.

Detecting Single Microwave Photons with NV Centers in Diamond. [PDF]
Materials (Basel), 2023 We propose a scheme for detecting single microwave photons using dipole-induced transparency (DIT) in an optical cavity resonantly coupled to a spin-selective transition of a negatively charged nitrogen-vacancy (NV−) defect in diamond crystal lattices.

Confined Nano‐NMR Spectroscopy Using NV Centers [PDF]
Advanced Quantum Technologies, 2020 Abstract Nano nuclear magnetic resonance (nano‐NMR) spectroscopy with nitrogen‐vacancy (NV) centers holds the potential to provide high‐resolution spectra of minute samples. This is likely to have important implications for chemistry, medicine, and pharmaceutical engineering.

Fluorescence modulation of nanodiamond NV- centers for neurochemical detection. [PDF]
MRS Adv, 2022 Nanodiamond (ND) with nitrogen vacancy (NV-) color centers has emerged as an important material for quantum sensing and imaging. Fluorescent, carboxylated ND (140 nm) is investigated for the detection of dopamine (DA), caffeine (CA), and ascorbic acid (AA). Over a 200 nM range, DA and CA quenched the ND fluorescence by 7.1 and 9.8%, respectively.

NV-plasmonics: modifying optical emission of an NV− center via plasmonic metal nanoparticles
Nanophotonics, 2022 Abstract The nitrogen-vacancy (NV) center in diamond is very sensitive to magnetic and electric fields, strain, and temperature. In addition, it is possible to optically interrogate individual defects, making it an ideal quantum-limited sensor with nanoscale resolution.
