Multifunctional Applications Enabled by Tunable Multi-Emission and Ultra-Broadband VIS-NIR Luminescence via Energy Transfer in Sn²⁺/Mn²⁺-Doped Lead-Free Zn-Based Metal Halides

Metal halides are widely applied in solid-state lighting (SSL), optoelectronic devices, information encryption, and near-infrared (NIR) detection due to their superior photoelectric properties and tunable emission. However, single-component phosphors that...
