Abstract: A quantum dot composition is described comprising light-emitting nanoparticles comprising a polyamine silicone ligand dispersed in a polymerizable resin composition comprising at least one polythiol, at least one polyene, wherein the polyene lacks functional groups that are amine-reactive, at least one amine-reactive ethylenically unsaturated component in an amount ranging from 2 to 15 wt.%, based on the total wt. % solids of the composition, and a hindered phenolic antioxidant. Also described are quantum dot (e.g. film) articles.

Abstract: A quantum dot article is described comprising a first barrier layer, a second barrier layer, and a quantum dot layer between the first and second barrier layer. The quantum dot layer comprises light-emitting nanoparticles dispersed in a cured matrix. The quantum dot layer further comprises a hydroxyl-iunctional polyamine silicone ligand that is the reaction product of a polyamine silicone ligand and a monofunctional epoxy compound. Also described is a hydroxyl-functional polyamine silicone that is the reaction product of a polyamine silicone and a monofunctional epoxy compound, as well as quantum dot compositions comprising light-emitting nanoparticles and the described hydroxyl-functional polyamine silicone.
