Ferroelectric Glass Nanoparticles, Liquid-Crystal Compositions, And Electronic Devices Containing The Nanoparticles
US Patent:
2013032, Dec 12, 2013
Filed:

Appl. No.:
13/712433
Inventors:
Dean R. Evans - Beavercreek OH, US

Assignee:
AZIMUTH CORPORATION - Dayton OH
International Classification:
C09K 19/54, B02C 23/08, B02C 17/00, G02F 1/1333, B03C 5/00
US Classification:
349182, 501 11, 501 53, 501 41, 501 40, 25229901, 65 339, 204571, 241 27, 241 243, 977773, 977900, 977952
Abstract:
Methods for preparing ferroelectric nanoparticles, liquid crystal compositions containing the ferroelectric nanoparticles, and electronic devices utilizing the ferroelectric nanoparticles are described. The methods of preparing the ferroelectric nanoparticles may include size-reducing a starting material comprising particles of a bulk intrinsically nonferroelectric glass to form glass nanoparticles having an average size of less than 20 nm, the glass nanoparticles comprising ferroelectric nanoparticles. Exemplary bulk intrinsically nonferroelectric glasses may include borosilicate glasses, tellurite glasses, bismuthate glasses, gallate glasses, and mixtures thereof, for example. The size reduction may be accomplished using ball milling with a solvent combination such as n-heptane and oleic acid. Liquid crystal compositions may include the ferroelectric nanoparticles in combination with a liquid crystal. Exemplary electronic devices include liquid crystal displays, in which a liquid crystal composition containing the ferroelectric nanoparticles is disposed adjacent a window material.

International Classification:
H01S 3/16, H01S 3/20, G02F 1/05
US Classification:
359342, 977778, 977779, 977834, 977838, 977951
Abstract:
The present invention provides a photorefractive hybrid cell including a window and a gain media disposed adjacent the window. The gain media includes nanoparticles therein. The window includes a material that forms a space-charge field. The gain media includes a material having refractive index properties that depend on an electric field. The nanoparticles include a material which responds orientationally to the presence of an electric or magnetic field.
Synergistcally Doped Potassium Niobate
US Patent:
7808080, Oct 5, 2010
Filed:

International Classification:
H01L 29/38, H01L 21/00
US Classification:
257607, 117 2, 257E29105
Abstract:
The present invention provides a photorefractive potassium niobate (KNbO) crystal including a first impurity added substitutionally to the niobium (Nb) site and a second impurity added substitutionally to the potassium (K) site, wherein the first and second impurities are different. There is also provided a method of making the codoped potassium niobate crystal (KNbO) of the present invention wherein the method includes adding at least one of the impurities to a melt composition during crystal growth, adding at least one of the impurities into an existing crystal using thermal diffusion, and/or adding at least one of impurities into an existing crystal using electrically assisted diffusion.
Field Generating Nanoparticles Doped In Light Valves
US Patent:
7889413, Feb 15, 2011

Assignee:
The Unites States of America as represented by the Secretary of the Air Force - Washington DC
International Classification:
G02F 1/07
US Classification:
359245, 359256
Abstract:
The present invention provides a method for automatically activating an optical light valve. The method includes providing a photorefractive cell having a birefringent medium which is doped with nanoparticles and transmitting light through the photorefractive cell to create an electric field in the photorefractive cell such that the alignment state of the birefringent medium and nanoparticles is changed to thereby reduce the intensity of the light being transmitted therethrough, wherein the intensity of light is reduces without an external power source.

Assignee:
United States of America as represented by the Secretary of the Air Force - Washington DC
International Classification:
G02B 6/34
US Classification:
385 37
Abstract:
The present invention provides a method for adjusting a diffraction grating to changes in ambient conditions. The method includes writing a diffraction grating in the photorefractive waveguide with a laser, measuring spectral characteristics of the diffraction grating, and allowing the diffraction grating to self-write from interference between a forward beam and a Fresnel reflection, such that the diffraction grating is adjusted for changes in ambient conditions.
