Defects in solids, for instance the NV− or the SiV− color center in diamond have proven their usability in many applications that require single quantum systems. Nanodiamonds (NDs) featuring single color centers are one possible platform that enables a scalable use of such systems. Functionalizing the NDs for their use in quantum optics and photonics experiments however remains a challenge. We present NDs hosting single negatively-charged silicon-vacancy (SiV−) centers featuring excellent optical properties, like a large Debye-Waller factor, close to Fourier-Transform limited linewidth and a narrow inhomogeneous distribution. We demonstrate nanomanipulation of the NDs, while conserving the optical properties denoting a first step towards the optical coupling of individual centers.
