Abstract
A particle comprising nanoparticles encapsulated within a host material is disclosed, wherein the particle includes a coating disposed over at least a portion of the outer surface of the particle. In certain embodiments, nanoparticles have light-emissive properties. In certain embodiments, the coating covers all or substantially all of the outer surface of the particle. The coating can comprise a resin having low oxygen permeability. In certain embodiments, the coating comprises a polyvinyl alcohol compound. In certain embodiments, the coating comprises a polyvinylidene dichloride compound. Other embodiments relate to a powder comprising a particle of the invention, a composition including a particle of the invention, a formulation including a particle of the invention, a coating comprising a particle of the invention, a method for making a particle of the invention, and products and applications including a particle of the invention. In preferred embodiments, a nanoparticle comprises a semiconductor nanocrystal.
