Abstract

Semiconductor nanocrystal structures having silica insulator coatings encapsulating the nanocrystals and methods of fabricating semiconductor nanocrystal structures having silica insulator coatings encapsulating the nanocrystals involve adding a silicon-containing silica precursor species to a solution of nanocrystals, subsequently forming a silica-based insulator layer on the nanocrystals from a reaction involving the silicon-containing silica precursor species, and adding additional amounts of the silicon-containing silica precursor species after initial formation of the silica-based insulator layer while continuing to form the silica-based insulator layer to finally encapsulate each of the nanocrystals.
