Optoelectronic device and stacking structure

An optoelectronic device, comprising:

• a light source;
• an emission layer disposed on the light source comprising a light emitting particle dispersed in a matrix polymer;
• a first polymer film consisting of an organic/inorganic hybrid polymer disposed directly on the emission layer;
• and a second polymer film disposed directly on the first polymer film,
• wherein the light emitting particle is a semiconductor nanocrystal selected from a Group II-VI compound, a Group III-V compound, a Group IV-VI compound, a Group IV element, a Group IV compound, or a combination thereof,
• the organic/inorganic hybrid polymer comprises a first moiety comprising a siloxane bond (—Si—O—Si—) a second moiety comprising a siloxane bond and at least one functional group, and a third moiety comprising a siloxane bond and a cross-linked structure of at least one reactive functional groups, and the organic/inorganic hybrid polymer is different from the matrix polymer, and
• the second polymer film consists of a polymerized product of a first monomer comprising with at least two thiol (—SH) groups, a second monomer comprising with at least two carbon-carbon unsaturated bond-containing groups at a terminal end, and at least one of a third monomer comprisin one thiol group located at a terminal end of the third monomer, a fourth monomer comprising one unsaturated carbon-carbon bond located at a terminal end of the fourth monomer, or a combination thereof.

A stacking structure comprising:

• a composite layer comprising a matrix polymer and a light emitting particle dispersed in the first matrix polymer;
• a first polymer film consisting of an organic/inorganic hybrid polymer disposed directly on the composite layer;

• wherein the light emitting particle is a semiconductor nanocrystal selected from a Group II-VI compound, a Group III-V compound, a Group IV-VI compound, a Group IV element, a Group IV compound, or a combination thereof,
• the organic/inorganic hybrid polymer comprises a first moiety comprising a siloxane bond (—Si—O—Si—), a second moiety comprising a siloxane bond and at least one functional group, and a third moiety comprising a siloxane bond and a cross-linked structure of at least one reactive functional groups, and the organic/inorganic hybrid polymer is different from the matrix polymer, and
• the second polymer film consists of a polymerized product of a first monomer with at least two thiol (—SH) groups and a second monomer with at least two carbon-carbon unsaturated bond-containing groups at a terminal end.
