Efficient coupling between quantum emitters and optical cavities is essential for scalable quantum photonic technologies. Group IV vacancy centers in diamond have emerged as promising candidates due to their spectral stability, high Debye-Waller factor and large orbital splitting in groundstates. Reduction of the diamond host size to the nanoscale enables new opportunities in terms of integration and scalability. However, creating optically coherent quantum emitters in nanodiamonds remains a major challenge. Here, we present the fabrication ofGroup IV color centers by means of ion implantation and describe the optical properties of the created color centers. We achieve high-purity singlephoton emission via resonant excitation and strong coherent drive. The obtained results demonstrate the potential of Group IV centers in nanodiamonds as a coherent single-photon source for quantum networks.
