Applications of nitrogen-vacancy centers in nanodiamonds for nanoscale thermometry and magnetometry

Abstract

Nitrogen-Vacancy (NV) center in diamond is a remarkable quantum system with exceptional electronic and optical properties. The NV center has been discovered in different charge states such as neutral, positive and negative. However, most of the research is conducted on the negatively charged NV center due to the fact that it can be useful for a wide range of applications. The distinct characteristics of NV centers are the position of the zero-phonon line and the temperature dependence of zero-phonon line emission relative to the phonon sidebands in the luminescence spectrum. The detection of electron spin resonance of NV center is the key for magnetometry. The brightness and I am deeply thankful to my Phd supervisor Dr. Taras Plakhotnik. Without his guidance, help and encouragement I would never be able to complete my Phd. His support and intellectual ideas were a source of motivation for me. Special thanks to Tara Massingham and Erinn Osmond for being kind and cooperative with me whenever I needed. Finally, I would like to thank my parents who supported me with their prayers. viii
