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

摘要

The invention relates to 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 invention also relates to the resulting water-compatible and organo-compatible composition of metal oxide nanocrystals.
