Abstract:
1. A water-stable semiconductor nanocrystal complex comprising: a semiconductor nanocrystal composition comprising a semiconductor nanocrystal core; a surfactant layer comprising molecules, each molecule having a moiety with an affinity for the semiconductor nanocrystal composition and a hydrophobic moiety with an affinity for a hydrophobic solvent; and an outer layer having hydrophobic sections for interacting with the surfactant layer and hydrophilic sections for interacting with an aqueous medium, wherein the semiconductor nanocrystal complex is chemically and electrically stable with a luminescent quantum yield of at least 10%, and wherein at least one of the hydrophobic moieties of the surfactant layer is cross-linked with at least one of the hydrophobic sections of the outer layer.
