Innovatively Continuous Mass Production Couette-taylor Flow: Pure Inorganic Green-Emitting Cs(4)PbBr(6) Perovskite Microcrystal for display technology

We report for the first time the mass production of Cs(4)PbBr(6) perovskite microcrystal with a Couette-Taylor flow reactor in order to enhance the efficiency of the synthesis reaction. We obtained a pure Cs(4)PbBr(6) perovskite solid within 3 hrs that then realized a high photoluminescence quantum...

Sumario:We report for the first time the mass production of Cs(4)PbBr(6) perovskite microcrystal with a Couette-Taylor flow reactor in order to enhance the efficiency of the synthesis reaction. We obtained a pure Cs(4)PbBr(6) perovskite solid within 3 hrs that then realized a high photoluminescence quantum yield (PLQY) of 46%. Furthermore, the Cs(4)PbBr(6) perovskite microcrystal is applied with red emitting K(2)SiF(6) phosphor on a blue-emitting InGaN chip, achieving a high-performance luminescence characteristics of 9.79 lm/W, external quantum efficiency (EQE) of 2.9%, and correlated color temperature (CCT) of 2976 K; therefore, this perovskite is expected to be a promising candidate material for applications in optoelectronic devices.
