Defect centers in large band gap solid state materials such as the NV− or the SiV− color center in diamond have proven as a reliable source for many quantum optical experiments. With almost bulk like optical properties, using nanodiamonds (ND) as a host for SiV− centers gives rise to flexible and scalable quantum systems. We investigate the optical properties of nanodiamonds and the influence of different preparation methods. Our work paves the way to quantum optical applications.
