Sb3+-doped 0D Cs3GdCl6 microcrystals with a near-unity photoluminescence quantum yield and high thermal quenching resistance for light-emitting application

All-inorganic lead-free luminescent metal halides doped with main-group ns2-electron ions have attracted considerable interest in a variety of optoelectronic applications. However, they normally suffer from severe thermal quenching of photoluminescence...
