PARTICLES INCLUDING NANOPARTICLES, USES THEREOF, AND METHODS

摘要

The present invention relates to a particle comprising nanoparticles encapsulated within a host material, 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. The coating can comprise a resin having low oxygen permeability and coating comprises a polyvinyl alcohol compound wherein the polyvinyl alcohol compound can optionally include one or more substituent groups, which can be the same or different. In preferred embodiments, a nanoparticle comprises a semiconductor nanocrystal. In certain embodiments, a host material comprises a polymer or an inorganic material.
