摘要: According to one embodiment, a product is a mixture including a solvent and generally spherical colloidal nanoparticles, the colloidal nanoparticles each having a core and a shell surrounding the core, and an electrode. In addition, the mixture is characterized as having a transparency to light in a predetermined wavelength range, where the transparency increases as a voltage of the electrode increases.

摘要: In one embodiment, a process includes creating a mixture of an aqueous component, nanowires and nanoparticles, and a hydrophobic solvent and allowing migration of the nanowires to the hydrophobic solvent, where the nanoparticles remain in the aqueous component. Moreover, the nanowires and nanoparticles are in the aqueous component before the migration.

摘要: A product includes a solution comprising Ag2Se quantum dots in a solvent. The solution is colloidally stable for at least one week. A product includes a solid layer formed of Ag2Se quantum dots. The layer is at least 100 nm thick. The layer is physically characterized by a substantial absence of defects therein. A process includes forming a solution of Ag2Se quantum dots and adding at least acetonitrile to the solution. The process further includes separating the Ag2Se quantum dots from the solution and washing the Ag2Se quantum dots at least two times in a solution comprising at least acetonitrile. The process further includes redispersing the washed Ag2Se quantum dots in a nonpolar solvent to create a colloidal suspension.

摘要: A product includes a cell having a mixture comprising a solvent and colloidal nanoparticles. Each of the colloidal nanoparticles have a core and a shell surrounding the core. The cell also includes at least one electrode. A product includes a nanoparticle having a core and a shell. The core includes a luminescent material. The shell is silicon-based. A method includes applying an external stimulus to a cell containing a mixture comprising a solvent and colloidal nanoparticles for altering the brightness and/or color of an assembly of at least some of the colloidal nanoparticles. Each of the colloidal nanoparticles have a core and a shell surrounding the core.
