Fluorescence profile of a nitrogen-vacancy center in a nanodiamond
Qiang Sun, Shuo Li, Taras Plakhotnik +1
Nanodiamonds containing luminescent point defects are widely explored for applications in quantum bio-sensing such as nanoscale magnetometry, thermometry, and electrometry. A key c…
Silicon-vacancy color centers in Si- and Si,P-doped nanodiamonds: thermal susceptibilities of photo luminescence band at 740 nm
Sumin Choi, Viatcheslav N. Agafonov, Valery A. Davydov +2
We have characterized thermal susceptibilities of the spectral band at 740 nm of silicon-vacancy (SiV) centers in Si- and Si,P-doped nanodiamonds over a temperature range from 295…
Ultrasensitive all-optical thermometry using nanodiamonds with high concentration of silicon-vacancy centres and multiparametric data analysis
Sumin Choi, Viatcheslav N. Agafonov, Valery A. Davydov +1
Nanoscale thermometry is paramount to study primary processes of heat transfer in solids and is a subject of hot debate in cell biology. Here we report ultrafast temperature sensin…
Relation between Raman backscattering from droplets and bulk water: Effect of refractive index dispersion
Taras Plakhotnik, Jens Reichardt
A theoretical framework is presented that permits investigations of the relation between inelastic backscattering from microparticles and bulk samples of Raman-active materials. It…
NV-centers in Nanodiamonds: How good they are
Taras Plakhotnik, Haroon Aman
This paper presents a method for determination of the size distribution for diamond nanocrystals containing luminescent nitrogen-vacancy (NV) centers using the luminescence intensi…
The electron-phonon processes of the nitrogen-vacancy center in diamond
Taras Plakhotnik, Marcus W. Doherty, Neil B. Manson
Applications of negatively charged nitrogen-vacancy center in diamond exploit the center's unique optical and spin properties, which at ambient temperature, are predominately gover…
All-optical thermometry and the thermal properties of the optically detected spin resonances of the NV center in nano-diamond
Taras Plakhotnik, Marcus W. Doherty, Jared H. Cole +2
The negatively-charged nitrogen-vacancy (NV) center in diamond is at the frontier of quantum nano-metrology and bio-sensing. Recent attention has focused on the application of high…
Optically Induced Polarization and Depolarization of an Electron Spin in a Nitrogen-Vacancy Center of Diamond Nano-crystals
Robert Chapman, Taras Plakhotnik
Pulsed laser excitation causes the luminescence of Nitrogen Vacancy centers in diamond to unexpectedly decrease with increasing pulse energy. This decrease is observed in both the…
Noise minimization in optical detection of small particle
Taras Plakhotnik
The ultimate sensitivity of optical detection is limited by the signal-to-noise ratio (SNR). The first part of the paper shows that coherence plays an important role in the noise a…
