Efficiency of Cathodoluminescence Emission by Nitrogen‐Vacancy Color Centers in Nanodiamonds

Small, 2017
Correlated electron microscopy and cathodoluminescence (CL) imaging using functionalized nanoparticles is a promising nanoscale probe of biological structure and function. Nanodiamonds (NDs) that contain CL-emitting color centers are particularly well suited for such applications.

Nitrogen-vacancy ensemble magnetometry based on pump absorption [PDF]

, 2018
We demonstrate magnetic-field sensing using an ensemble of nitrogen-vacancy centers by recording the variation in the pump-light absorption due to the spin-polarization dependence of the total ground-state population.
