Abstract:
1. An optoelectronic device, comprising: a light source; an emission layer disposed on the light source comprising light emitting particles dispersed in a matrix polymer; and a polymer film disposed on the emission layer, wherein the light emitting particle comprises a semiconductor nanocrystal selected from a Group II-VI compound, a Group III-V compound, a Group IV-VI compound, a Group IV compound, or a combination thereof, wherein the polymer film comprises a first polymer layer comprising a first polymer and a second polymer layer comprising a second polymer, wherein the first polymer comprises a polymerized product of a first monomer comprising at least two thiol (—SH) groups and a siloxane-containing second monomer or oligomer comprising at least one carbon-carbon unsaturated bond at a terminal end, wherein the second polymer comprises a polymerized product of a third monomer comprising at least two thiol (—SH) groups and a fourth monomer comprising at least two carbon-carbon unsaturated bonds at a terminal end, and wherein the first polymer layer is disposed directly on the emission layer, and the second polymer layer is disposed directly on the first polymer layer.
