Multifunctional applications enabled by tunable multi-emission and ultra-broadband VIS-NIR luminescence via energy transfer in Sn 2+ /Mn 2+ -doped lead-free Zn-based metal halides

Tunable multi-emission and ultra-broadband visible to near-infrared luminescence in Sn 2+ /Mn 2+ -doped lead-free Zn-based metal halides have been achieved by adjusting the doping ratios and excitation wavelengths.
