Diamond color center has fluorescence stability at room temperature and good biocompatibility, and can be used as an excellent single photon source or fluorescent marker in the fields of quantum information transmission and biological fluorescent labeling. Compared with the traditional diamond nitrogen-vacancy (NV) color center, the diamond silicon-vacancy (SiV) color center shows better optical properties, including narrower phonon sideband, shorter excited state lifetime and more concentrated fluorescence radiation. This paper mainly introduces the structural properties and application prospects of diamond SiV color centers, compares the differences between SiV color centers and NV color centers in physical parameters and application fields, and introduces several common preparation methods of SiV color centers.
