Nitrogen-vacancy color centers in diamond and their applications in sensing and imaging

The negatively-charged nitrogen-vacancy (NV^-) color centers in diamond allow for sensing magnetic and electric fields, and temperature changes over micro- and nano-meter scales. I will discuss the underlying physics of NV centers and various sensing modalities with particular focus on the, so called, optically detected magnetic resonance. I will then introduce magnetometry applications and high-resolution magnetic field imaging. Finally, I will discuss our results on the development of hybrid glass-diamond sensors and on biology-oriented studies with NV diamonds.
