摘要:
A method of manufacturing an LED lamp includes dispersing color correction particles throughout a suspension media to a viscosity of substantially 2000 cP. In the case of correcting blue GaN LEDs to white light, the particles to be blended are phosphorus having a diameter of less than 20 microns. An LED die is mounted onto a stage and a nano-liter pipette is arranged such that an interface separation of approximately 1 millimeter is achieved between the tip of the pipette and the surface of the LED die. Once the relatively viscous suspension media covers the LED die, ultraviolet light is directed towards the suspension media to cure it. Heat is then applied to further cure the suspension media until solid as observed under a microscope.

Methods and apparatus for the preparation and use of a substrate having an array of diverse materials in predefined regions thereon. A substrate having an array of diverse materials thereon is generally prepared by delivering components of materials to predefined regions on a substrate, and simultaneously reacting the components to form at least two materials. Materials which can be prepared using the methods and apparatus of the present invention include, for example, covalent network solids, ionic solids and molecular solids. More particularly, materials which can be prepared using the methods and apparatus of the present invention include, for example, inorganic materials, intermetallic materials, metal alloys, ceramic materials, organic materials, organometallic materials, non-biological organic polymers, composite materials (e.g., inorganic composites, organic composites, or combinations thereof), etc. Once prepared, these materials can be screened for useful properties including, for example, electrical, thermal, mechanical, morphological, optical, magnetic, chemical, or other properties. Thus, the present invention provides methods for the parallel synthesis and analysis of novel materials having useful properties.

The apparatus comprise a first region comprising a first nucleation catalyst material and a second region comprising a second nucleation catalyst material, with the first and second regions positioned adjacent to each other and configured to support at least one crystal, and with the first region having a variation in a nucleation property of the first nucleation catalyst material in the first region. The crystal may be supported at an interface of the adjacent regions. The methods comprise providing a first region of a first nucleation catalyst material and a second region of a second nucleation catalyst material adjacent said first region, with the first region having a variation in a nucleation property of the first nucleation catalyst material, exposing the first and second regions to a solution of a selected molecule, and growing at least one crystal of the molecule in association with the first and second regions.

Self-glowing phosphorescent blends comprises of silicates, phosphate, and their compounds with aluminates (e.g. alumino-silicates and alumino-phosphate) phosphors are disclosed. These blends can be optically charged by exposure to sunlight or artificial light sources, and are able to emit visible light for hours in darkness without the need of electricity or consumption of materials. Such optical charging-discharging cycles can be repeated at least 1000 times. These blends can be used to form many commercial products and used in many applications such as: self-glowing paints or coating blends, self-glowing adhesive tapes, self-glowing foils, self-glowing glues and sealants, self-glowing ceramic glazes, self-glowing writing and printing inks, self-glowing papers and stickers, self-glowing textiles and cloth, self-glowing glasses, and self-glowing plastic composites. The “self-glowing” refers to the ability to emit visible light or photon, without simultaneously being externally excited, or consumption of energy (like lamps) or materials (like candle) at the same time. These self-glowing blends or composites can glow in the darkness without consuming electricity and can be utilized in the following applications: 1. Self-glowing marking, labeling, decoration, film coating, and paintings on the body of bicycles, automobiles, ships, and aircrafts. Such utility will display the contour, the location, and color of the subject's body at night or in darkness with the benefits of decoration and safety of traveling. 2. Self-glowing marking, labeling, decoration, film coating, and paintings on the walls, the swimming pools, stairs, steps, and other outstanding objects inside or outside of a building. Beside apparent decoration utility in the darkness, they can also show the contour or locations of the objects in the darkness to avoid injury related liability. 3. Low-level lighting source, i.e. “Electric less” lamps. By applying the blend on artificial lamp surfaces, they can self-glow in the darkness for hours after lamp is turned off. When lamp is back on, they can be optically excited and charged up, while shifting the lamp color to longer wavelength and warmer appearance. 4. The blends can be utilized in many other special self-glowing products to save electricity and pollution and prevent safety hazards in darkness. For example, self-glowing paper and ink will allow people to write in the darkness without need for lamps. Self-glowing paint, tapes, ceramic glaze, and labels will allow people to act in the darkness without the need for electric lamps. Self-glowing glass and plastic articles will decorate or display at night without need for electric lamps. Besides conserving electricity and environment, self-glowing products may be used to direct traffic and prevent injury associated with power outage or electric lamps failure. These products also provide convenient safety measures in products such as self-glowing textiles that pedestrian and bicyclists can wear at night, without the need for electric lamps.

摘要:
Viewable images may be displayed from a substantially dark substrate. Light emitting material may be integrated into a substantially dark substrate. The light emitting material may be configured to emit visible light in response to absorption of ultraviolet light. The light emitting material may include a plurality of light emitting particles and each of the plurality of light emitting particles has a diameter less than about 500 nanometers. For example, emitting visible light from a substantially dark substrate may allow for images to be displayed with relatively high contrast. These high contrast images may appear clearer to a viewer and may result in less eye strain by a viewer.

摘要:
An electron emitter includes a coating layer of a mixture of carbon nanotubes and alkaline-earth metal oxides on an electrically conducting structure. The preferred carbon nanotubes are those having a diameter less than about 200 nm. A substantial portion of electron emission is liberated from the carbon nanotubes, thus lessening the requirement on the alkaline-earth oxides. Such an electron emitter is advantageously used in gas discharge devices to increase the energy efficiency thereof.
摘要:
In accordance with embodiments, viewable images can be created in glass. Viewable images may be created in glass by using a projector which projects ultraviolet light to excite light emitting material. Clear images may be created in glass because the size the light emitting particles in the glass is less than 400 nanometers. In embodiments, the visible illumination of a transparent substrate to display an image is possible, while the transparent substrate remains transparent. Accordingly, for example, drivers of automobiles may view images (e.g. map images) on their windshield while they are driving. As another example, window shoppers may view enhanced advertisements in the windows of stores that they are approaching.
