摘要： A method for producing a phosphor made of luminous inorganic particles of a nanostructure which is capable of keeping a surface of the phosphor from being polluted by any by-product and controlling a particle diameter distribution of the phosphor as desired. A carbon material and an inorganic salt are mixed together to prepare a mixture, which is then heated, to thereby form an interlaminar compound. Then, the interlaminar compound is subject to a treatment using an eliminating agent, leading to production of luminous inorganic compound particles adhered to the carbon material.

摘要： A field emission type electron source capable of permitting a resistance value between a cathode wiring and each of emitter cones to be set at substantially the same level and increasing packaging density of the emitter cones. The electron source includes stripe-like cathode wirings arranged on an insulating substrate. The cathode wirings each are formed with a plurality of windows, so that a plurality of island-like cathode conductors and resistance layers different in resistance value from each other are formed separate from the cathode wiring. Then, a resistance layer, an insulating layer and a gate electrode are formed thereon. The gate electrode and insulating layer are formed with apertures in a manner to be common to both, in which the emitter cones are arranged, resulting in emission of electrons from the emitter cones of each group unit being rendered uniform.

摘要： A field emission type display device capable of providing display with gradation and permitting the whole display device to be integrated with a display drive circuit section. Memory sections are arranged in correspondence to image cell sections, resulting in static display being accomplished. Also, Light emission of an anode is carried out depending on data held in the memory section, so that a luminous period is increased and adequate luminance is provided at a drive voltage substantially lower than that required for dynamic display. An FEC element is incorporated in each of the memory sections in correspondence to incorporation of an FEC element in each of the image cell sections, so that the image cell sections and memory sections may be concurrently manufactured during manufacturing of the FEC elements, to thereby significantly simplify manufacturing of display device.

摘要： A field emission element including a gate and an emitter and capable of preventing any of the element oxide layer from being formed on a tip of the emitter to prevent a decrease in emission current, unstable operation and an increase in noise. The gate has a surface formed of a material of oxygen bonding strength higher than that of a material for at least a tip surface of the emitter, so that oxygen atoms and molecules containing oxygen entering the gate may be captured by adsorption on the gate to prevent formation of any oxide layer on the emitter. When a portion of the emitter other than the tip surface is formed of a material of oxygen bonding strength higher than that of the material for the tip surface, formation of any oxide layer on the tip surface of the emitter is minimized.
