摘要： There is disclosed a luminescent phosphor having an average particle size of less than about 3 microns, as well as a bright luminescent phosphor having an average particle size of less than 5 microns and a luminescence of about 10-12 au. The bright luminescent phosphor is made by combing a yttrium or gadolinium host material with a europium dopant in a liquid to form a slurry, and then pulverizing the slurry to less than about 3 microns in average particle size. The pulverized slurry is then heated to yield the bright luminescent phosphor. The bright luminescent phosphor is particularly suited for use in high resolution display screens, and in screens which require low power consumption, such as laptop computers.

摘要： A process for operating a field emission display (FED) is disclosed. The FED has a faceplate and a baseplate, and a layer of praseodymium-manganese oxide disposed between the faceplate and baseplate. The layer absorbs photons during operation of the FED, and thus provides for improved performance of the FED because, for example, stray photons do not impact the underlying circuitry of the FED.

摘要： A process is provided for forming spacers useful in large area displays. The process comprises steps of : forming bundles or boules comprising fiber strands which are held together with a binder; slicing the bundles or boules into slices; adhering the slices on an electrode plate of the display; and removing the binder. In the step of forming bundles or boules comprising fiber strands, the function of the binder is initially or fully performed by glass tubings surrounding the glass fibers. The clad glass of the envelopes etches more readily than the core glass.

摘要： A multi-stage process for preparing a phosphor product includes the stages of selecting precursors of a dopant and a host lattice as the phosphor starting materials, grinding the starting materials in an initial grinding stage for an initial grinding time period to produce an initial ground material having a smaller particle size distribution than the starting materials, firing the initial ground material in an initial firing stage at an initial firing temperature for an initial firing time period to produce an initial fired material, grinding the initial fired material in an intermediate grinding stage for an intermediate grinding time period to produce an intermediate ground material having a smaller particle size than the initial fired material, wherein the intermediate grinding time period is substantially less than the initial grinding time period, firing the intermediate ground material in an intermediate firing stage at an intermediate firing temperature for an intermediate firing time to produce an intermediate fired material, wherein the intermediate firing temperature is substantially greater than the initial firing temperature, grinding the intermediate fired material in a final grinding stage for a final grinding time period to produce a final ground material having a smaller particle size than the intermediate fired material, and firing the final ground material in a final firing stage at a final firing temperature for a final firing time to produce a phosphor product, wherein the final firing time is substantially less than the intermediate firing time.

摘要： A display device and a method for making and operating the display device are described. The display device comprises a base plate containing at least one emitter, a display screen, and a spacer located between the base plate and display screen, where the spacer has a high concentration of an emitter-cleaning material. The spacer may comprise a xerogel or aerogel material and the emitter-cleaning material may comprise hydrogen. The spacer and a method for making the spacer and using the spacer to clean an emitter are also described. The spacer material cleans the emitter by absorbing gases during fabrication of the display device and desorbing emitter-cleaning gases during operation of the display device. By keeping the emitter clean, the spacer retains the work function of the emitter at a low level, thereby prolonging the usefulness of the display device.
