METHOD FOR PREPARING A WATER-COMPATIBLE COMPOSITION OF METAL OXIDE NANOCRYSTALS

摘要

A method for preparing a composition of metal oxide nanocrystals from at least one organometallic precursor in an aprotic solvent in the presence of at least one PEG ligand including a carbon chain having at least one end functionalized by a coordinating group containing at least one heteroatom, and at least one [—OCH2CH2]n, group, such that it is soluble in both the aprotic solvent medium and in water. The resulting water-compatible and organocompatible composition of metal oxide nanocrystals is also described.
