Abstract
A nanoparticle multilayer thin film is provided in which nanoparticles which are not electrically insulated from each other are spaced apart from one another at a reduced distance. The nanoparticle multilayer film includes: at least one first nanoparticle layer including first nanoparticles that are surface-modified with a cationic metal-chalcogenide compound; and at least one second nanoparticle layer including second nanoparticles that are surface-modified with an anionic metal-chalcogenide compound, wherein the first nanoparticle layer and the second nanoparticle layer are alternately stacked upon one another.
Claims13
A nanoparticle multilayer film comprising:
- at least one first nanoparticle layer comprising first nanoparticles, said first nanoparticles being surface-modified with a cationic metal-chalcogenide compound;
- and
- at least one second nanoparticle layer comprising second nanoparticles, said second nanoparticles being surface-modified with an anionic metal-chalcogenide compound,
- wherein the first nanoparticle layer and the second nanoparticle layer are alternately stacked upon one another, and
- wherein the cationic metal-chalcogenide compound and the anionic metal-chalcogenide compound are covalently bonded molecules, and wherein the cationic metal-chalcogenide compound is directly bonded to the surface of the first nanoparticles.
