Nanodiamonds are tiny diamond particles only a few nanometers in size. Because they are chemically highly stable and can host so-called color centers, optically active defects in the crystal lattice, they are considered promising materials for quantum technologies, sensing and biomedical research. U ntil now, however, it has been difficult to reliably produce nanodiamonds with uniform size, high purity and precisely integrated optical properties. ...read more read less
