Abstract

An article of manufacture comprising doped, colloidal nanostructures that are configured to have a plasmonic response to light of a first resonance wavelength.

Claims (9)

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).
