Abstract: A luminous gas discharge display including at least two opposing hermetically sealed plates. At least one of the plates is formed of a transparent material and cooperatively forms with at least one other plate at least one channel. The channel contains an ionizable gas to define a gas discharge path. The display further includes at least one pair of electrodes in communication with the at least one channel. At least one of the electrodes is a flat electrode positioned internally between the plates and includes a conductive material deposited on the channel and extending from the channel to outside the periphery of the display to provide electrical contact between a voltage source and the ionizable gas to produce a gas discharge display.

Abstract: An electron emitter (2) has a semiconductor substrate (20) doped with an n-type region (21). A diamond layer (24) is doped by ion implantation with a p-type dopant to form a graded dopant profile region (27) that increases away from the upper surface of the diamond layer (24) and a thin insulating region (28) separating the p-type region (27) from the n-type region (21). The emitter (2) has a first electrical contact (23) on a lower surface of the substrate (20) and a second electrical contact (25) on the upper surface of the diamond layer (24) such that a voltage can be applied across the emitter (2) to cause tunneling of electrons from the n-type region (21) through the insulating region (28) into the p-type region (27), causing emission of electrons from an exposed surface (29). A lamp or display (1) includes several such electron emitters (2) and contains gas at reduced pressure, which is ionized by the emitted electrons, thereby generating UV radiation, which causes a fluorescent layer (5) on a transparent window (3) to produce visible light.

Abstract: A coated coil emissive electrode of the type utilized in fluorescent lamps and a method for making such an electrode. The electrode includes a tungsten coil, a bonding layer of an emissive form of barium tungstate coating said tungsten coil, and a layer of porous barium oxide coating said barium tungstate, said barium tungstate bonding said barium oxide to said tungsten coil. The electrode is made by coating said tungsten coil wuth a mixture of barium peroxide, cellulose nitrate and butyl cellosolve and heating said coated coil to the exothermal decomposition temperature of said cellulose nitrate. The exothermal decompositon of said cellulose nitrate raises the temperature of the barium peroxide to its exothermal decomposition temperature thereby forming said bonding layer of the emissive form of barium tungstate and releasing bubbles of oxygen causing the pores in said barium oxide.
