Sb 3+ –doped 0D Cs 3 GdCl 6 microcrystals with a near-unity photoluminescence quantum yield and high thermal quenching resistance for light-emitting application

A new class of luminescent materials based on Sb 3+ –doped 0D Cs 3 GdCl 6 microcrystals featuring a near-unity quantum yield (QY) and good thermal quenching resistance ( I 150°C = 82.4%) are developed and explored for white light-emitting diodes.
