Abstract
A method of forming dispersed water-soluble quantum dots and tuning water-soluble quantum dot aggregate size by providing a plurality of water-soluble quantum dots in a dispersion, the plurality of water-soluble quantum dots are modified with an amphiphilic polymer, and by adding an amount of the amphiphilic polymer to the dispersion such that the ratio of the amphiphilic polymer units to quantum dots is maintained higher to obtain dispersions of smaller quantum dot aggregates and kept lower to obtain dispersions of larger quantum dot aggregates.
