A method is provided for making a fabric. The method comprises (a) providing a composition comprising a plurality of nanocrystals disposed in a liquid medium, the nanocrystals comprising a material elected from the group consisting of a Group IV element; (b) applying the composition to a porous substrate, thereby removing at least a portion of the liquid medium from the nanocrystals; and (c) removing the nanocrystals from the porous substrate as a self-supporting mass.

Group IV metal or semiconductor nanowire fabric

A method for the production of a robust, chemically stable, crystalline, passivated nanoparticle and composition containing the same, that emit light with high efficiencies and size-tunable and excitation energy tunable color. The methods include the thermal degradation of a precursor molecule in the presence of a capping agent at high temperature and elevated pressure. A particular composition prepared by the methods is a passivated silicon nanoparticle composition displaying discrete optical transitions.

Applications of light-emitting nanoparticles

Light strips for emergency lighting, path lighting, accent lighting and device lighting are provided. Devices incorporating and lighted by the light strips are also provided. The light strips include a light emitting layer made from a plurality of semiconductor nanoparticles disposed between and in electrical communication with an anode and a cathode. The semiconductor nanoparticles may be made from Group IV semiconductors, such as silicon. Devices that may be lit with the light strips include displays and keypad, such as those found in cellular phones and personal digital assistants.

Light strips for lighting and backlighting applications

This invention provides a phosphor material capable of absorbing primary light and converting that light into white light having a high color rendering index and illumination devices made from the phosphor material. The white light may have a color rendering index of 100 and may be produced with an efficiency of at least 30 lm/w. In one embodiment, the illumination device includes a secondary light source made from a plurality of Group IV semiconductor nanoparticles.
