Quantum sensing using optically addressable atomic-scale defects, such as the nitrogen-
vacancy (NV) center in diamond, provides new opportunities for sensitive and highly …

Luminescent carbon-based nanomaterials have inspired tremendous research interests due
to their tunable optical properties as well as superior biocompatibility. In this review, distinct …

Extension of nuclear magnetic resonance (NMR) to nanoscale samples has been a
longstanding challenge because of the insensitivity of conventional detection methods. We …

Fluorescence bioimaging is a powerful, versatile, method for investigating, both in vivo and
in vitro, the complex structures and functions of living organisms in real time and space, also …

Photoluminescent nanosized allotropes of carbon have attracted considerable interest
because of their diverse optical properties depending on their crystal structure, size, and …

We present measurements of spin relaxation times (T 1, T 1 ρ, T 2) on very shallow (≲ 5 nm)
nitrogen-vacancy centers in high-purity diamond single crystals. We find a reduction of spin …

We report an experimental study of the longitudinal relaxation time (T 1) of the electron spin
associated with single nitrogen-vacancy (NV) defects hosted in nanodiamonds (NDs). We …

We show how the interference between spatially separated states of the center of mass (cm)
of a mesoscopic harmonic oscillator can be evidenced by coupling it to a spin and …

Nitrogen–vacancy (NV) centres in diamond are attractive for research straddling quantum
information science,,,,,,,, nanoscale magnetometry,,,, and thermometry,. Whereas ultrapure …

We report successful introduction of negatively charged nitrogen-vacancy (NV–) centers in a
5 nm thin, isotopically enriched ([12C]= 99.99%) diamond layer by CVD. The present …
