ELECTROLUMINESCENT CROSSLINKED NANOCRYSTAL FILMS

摘要

The present invention relates to an emissive film comprising a network of crosslinked nanocrystals, wherein said network of crosslinked nanocrystals is formed from reactive colloidal nanocrystals comprising a core comprising a semiconductive compound and at least one polythiol ligand, and wherein said core is surrounded by at least one polythiol ligand, and wherein each core surrounded by at least one polythiol ligand is crosslinked with at least one another polythiol ligand surrounding another core. The photoluminescent properties of the NCs are preserved once the film is formed. A light emitting device (LED) is fabricated using an emissive film as the emissive layer. The LED emits light when an electrical current flows through the device, which proves the electroluminescent properties of the NCs film.
