Abstract
A method to modify the surface of III-V quantum dots. III-V quantum dots provided with X type ligands and L type ligands at their outer surface are dispersed in a solvent include an additional compound. The additional compound has an organic acid of formula RYH or an organic salt of formula RYH+Z− and has at least one acidic proton H+ having a pKa in water equal to or lower than 16. During dispersion the acidic proton H+ protonates at least part of the L type ligands and at least part of the X type ligands are replaced. Surface modified quantum dots, dispersions having such surface modified quantum dots and to the use of such dispersions are disclosed.
