摘要：Article comprising particles in an organic polymer matrix comprising a curedthiol-alkene resin having a T>20° C., wherein the particles comprise a composite core anda continuous nonmetallic inorganic coating covering the composite core, wherein thecomposite core comprises a nonmetallic inorganic matrix, ligands, and quantum dots,wherein the nonmetallic inorganic matrix is present in the composite core in an amount ofup to 40 volume percent, and wherein the coating has an average thickness up to 5micrometers. Exemplary articles described herein can be made for use in display

applications such as films, LED caps, LED coatings, LED lenses, and light guides. Exemplaryarticles described herein can be made for use in nondisplay applications such as securityapplications where quantum dot phosphors are used to provide fluorescence at selectedor tailored wavelengths. In such uses, the organic polymer matrix could be a label or acoating on a label, or other articles such as a card or tag.
