Abstract
The invention is in the field of nanostructure synthesis. Provided are highly luminescent nanostructures, particularly highly luminescent quantum dots, comprising a nanocrystal core/shell and a thin metal oxide on the outer shell of the nanostructure. Also provided are methods of preparing the nanostructures, films comprising the nanostructures, and devices comprising the nanostructures.
