Abstract
A method for preparing a quantum dot mixture with a bimodal size distribution includes steps of: a) preparing a mixed cationic precursor solution, b) preparing a first anionic precursor solution and a second anionic precursor solution, c) conducting a nucleation reaction at a nucleation temperature for a predetermined nucleation time, and d) conducting a crystallite growth reaction at a crystallite growth temperature for a predetermined crystallite growth time.
