Abstract
The present application discloses a preparation method for quantum dots (QDs). The method includes providing initial QD cores, and mixing the initial QD cores with an organic carboxylic acid to bond the organic carboxylic acid to the surface of the initial QD cores; preparing a shell layer on the surface of the initial QD cores in a shell-growth reaction system containing an organic carboxylic acid; and mixing and heating the solution system, obtained after a completion of shell-layer growth reaction, with an organic amine, an organic phosphine, or a mixed solution of the organic amine and the organic phosphine.
