摘要：

The enhancement of the zero phonon line (ZPL) emission of the red⁃emitting Mn4+⁃activated phosphors, will lead to the enhancement of the short wavelength emission in the whole luminescence spectrum, and usually the luminescence will decay faster. The Mn4+-activated fluoride phosphors with intense ZPL， 28 kinds in total， with intense zero phonon line （ZPL） emission were reviewed， on aspects of the chemical composition， preparation method， crystal structure and photoluminescence property. Several rules were found：（1） The Mn4+-activated fluoride phosphors with intense ZPL can be classified into four categories based on whether Mn4+ is equivalent with the cation being substituted and whether the substituted cations form octahedral coordination structures in the matrix. （2） Distortion of the ［MnF6］ coordination octahedra after doping is necessary to achieve intense ZPL. （3） For most of the fluoride phosphors with intense ZPL， the Mn4+ doping is heteroequivalent， substituting a cation with 3+ valence state； when the substituted ion is tetravalent and six-coordinated， the crystal structure achieving intense ZPL emission is mainly in trigonal crystal system with space group such as P321 and P3m1. （4） For most of the fluoride phosphors with intense ZPL， the intensity of ZPL is weaker than that of Stokes ν6 phonon sideband emission （except for five kinds like Na2TiF6∶Mn4+ in which the ZPL is more intense than the ν6 peak）. （5） Their ZPLs are located within 617-628 nm， mainly at 620 nm. （6） The ZPL/ν6（Stokes） intensity ratio is not only dependent on the chemical composition of the phosphor， but also varies with the preparation method for a specific phosphor. © 2023 Chines Academy of Sciences.
