Over the last decade color centers in diamond have proven to be promising candidates for quantum optics applications [1]. For applications like sensing or cQED it is advantageous to use color centers in nanodiamonds (NDs). However these color centers often exhibit inferior optical qualities compared to bulk diamonds. Although for example spectral properties for silicon vacancies centers have recently been improved dramatically [2], issues like blinking and spectral defusion remain.
Therefore investigating the optical properties for color centers in NDs is an important goal. We are testing methods to increase their optical and coherence properties. The analysis is done with confocal spectroscopy at room and cryogenic temperatures. In the future we aim to incorporate these color center in NDs into cQED experiments.
