Abstract
A method of the present disclosure for producing methylammonium lead halide perovskite quantum dots includes providing a Pb-oleic acid solution containing a Pb source that is soluble in oleic acid, oleic acid, and a non-polar solvent, providing a methylammonium-oleic acid solution containing methylammonium acetate and oleic acid, providing a reaction solution of tetrabutylammonium halide and oleylamine, and mixing the Pb-oleic acid solution, the methylammonium-oleic acid solution, and the reaction solution.
