Claim 0:
1. A preparation method for quantum dots (QDs), comprising:
providing initial QD cores, and mixing the initial QD cores and an organic carboxylic acid according to a mass-molar ratio of 10 mg of the initial OD cores to (3˜10) mmol of the organic carboxylic acid, and/or heating the initial QD cores with the organic carboxylic acid at a temperature condition of 80˜150° C. for 20˜60 minutes to bond the organic carboxylic acid to a 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 a 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.
