Abstract
Official abstract text for this publication.
An article of manufacture comprising doped, colloidal nanostructures that are configured to have a plasmonic response to light of a first resonance wavelength.
First claim
Opening claim text (preview).
What is claimed is: 1. An article of manufacture comprising doped, colloidal nanostructures that are configured to have a plasmonic response to light of a first resonance wavelength, wherein the doped, colloidal nanostructures are dispersed in a solution deposited on a flexible surface, and wherein the doped, colloidal nanostructures comprise an optical switch that, in response to an absence of light at the first resonance wavelength, has a first light absorption level and, in response to a presence of light at the first resonance wavelength, has a different second light absorption level. 2. The article of manufacture of claim 1 , wherein the doped, colloidal nanostructure is doped with aliovalent dopants. 3. The article of manufacture of claim 2 , wherein the doped, colloidal nanostructures comprise zinc oxide (ZnO) nanostructures. 4. The article of manufacture of claim 3 , wherein the doped, colloidal nanostructures are doped with at least one of aluminum, gallium, and indium. 5. The article of manufacture of claim 2 , wherein the doped, colloidal nanostructures comprise indium oxide (In 2 O 3 ) nanostructures. 6. The article of manufacture of claim 5 , wherein the doped, colloidal nanostructures are doped with at least one of tin and antimony. 7. The article of manufacture of claim 2 , wherein the doped, colloidal nanostructures comprise cadmium oxide (CdO) nanostructures. 8. The article of manufacture of claim 7 , wherein the doped, colloidal nanostructures are doped with at least one of tin, aluminum, gallium, indium, and fluorine. 9. The article of manufacture of claim 1 , wherein the optical switch is configured to switch between the first light absorption level and the second light absorption level in less than 1 picoseconds (ps).
