Self-trapping excitons (STEs) emission in metal halides has been a matter of interest, correlating with the strength of electron-phonon coupling in the lattice, which are usually caused by ions with ns2electronic structure. In this work, Sb3+/Te4+ions doped Zn-based halide single crystals (SCs) with two STEs emissions have been synthesized and the possibility of its anti-counterfeiting application was explored. Further, the relationship between the strength of electron-phonon coupling and photoluminescence quantum yields (PLQYs) for STEs in a series of metal halides has been studied. And the semi-empirical range of the Huang-Rhys factors (S) for metal halides with excellent photoluminescence (PL) property has been summarized. This work provides ideas for further research into the relationship between luminescence performance and electron-phonon coupling of metal halides, and also provides a reference for designing the metal halides with high PLQYs. |
