Optical and microwave spectroscopy of colour centres in nanodiamonds

In this presentation, I will discuss the key features of colour centres in diamonds, which have many applications in magnetometry, sensor systems and quantum information science. The main part od the presentation will be focused on important spectral characteristics of vacancy-related colour centres and analysis by optically detected magnetic resonance (ODMR), which is a double resonance techinique that enables the transitions between spin sublevels to be detected by optical means.
