Abstract
Official abstract text for this publication.
A conductive nanowire film having a high aspect-ratio metal is described. The nanowire film is produced by inducing metal reduction in a concentrated surfactant solution containing metal precursor ions, a surfactant and a reducing agent. The metal nanostructures demonstrate utility in a great variety of applications.
First claim
Opening claim text (preview).
The invention claimed is: 1. A film comprising a plurality of nanowire bundles, each nanowire bundle comprising a plurality of conductive metal nanowires, the plurality of conductive metal nanowires comprising conductive metal nanowires having cross-sectional diameters between 3 and 5 nm and aspect-ratios of more than 500, wherein the conductive nanowires being a composite of 85-90% gold and 10-15% silver. 2. The film according to claim 1 , wherein said aspect-ratio is greater than 1,000. 3. The film according to claim 1 comprising at least one surfactant. 4. The film according to claim 1 , formed on a substrate. 5. The film according to claim 1 , wherein the nanowires are distributed in a film of at least one surfactant. 6. A device comprising a film according to claim 1 . 7. The device according to claim 6 being selected from an electrode structure, being optionally configured as a photocathode, a photocathode structure having an optically transparent substrate carrying said film, an optically transparent electrode, an electronic device having an electrodes' assembly, a transistor device wherein at least one of source, drain and gate electrodes comprises said film, a transistor device comprising a gate on an insulator structure comprising an electrically insulating substrate carrying said film, and an electroluminescent screen device comprising a luminescent substrate structure carrying said film.
