This application is a continuation of International Application No. PCT/US2012/066137, filed 20 Nov. 2012, which was published in the English language as International Publication No. WO 2013/078242 on 30 May 2013, which International Application claims priority to U.S. Provisional Patent Application No. 61/562,457, filed on 22 Nov. 2011. Each of the foregoing is hereby incorporated herein by reference in its entirety for all purposes.

The present invention relates to semiconductor nanocrystals, also referred to as quantum dots, and to methods of coating or providing layers on quantum dots.

Methods of making quantum dots are in the literature. For example, see US 20106849, U.S. Pat. No. 7,476,599 and WO 2009/120688. However, additional methods of making quantum dots with coatings or layers are desirable.

The present invention relates to quantum dots including an overcoating, methods for overcoating quantum dots, materials and products including quantum dots taught herein, and materials and products including quantum dots made by a method taught herein.

Embodiments of the present invention are directed to methods of providing one or more coatings or layers or shells on quantum dots. According to one aspect, a quantum dot to be provided with a coating or layer or shell may be referred to as a “core” particle or a “core” quantum dot. According to an additional aspect, the core particle is subjected to a high temperature process that forms a coating or layer or shell on the core particle to produce a core-shell quantum dot.
