Abstract: An absorbing coating consisting of three layers sequentially deposited on e aluminized phosphor screen of an electro-optical device such as an image intensifier. The layers are: a transparent dielectric layer with a thickness of about one quarter wavelength of radiation to be absorbed, a thin metal semitransparent layer, and an aluminum oxide protective layer for the thin metal layer. The coating is transparent to electrons bombarding the phosphor, but absorbs radiation which might pass through the photocathode and be reflected from the phosphor aluminum coating back to the photocathode. Such reflected radiation can cause spurious output electrons from the photocathode.

Abstract: This invention relates to the art of coating glassware while the ware is moving through an annealing lehr which is provided with a cooling section near the exit end of the lehr. The cooling section is of the continuous recirculation type providing an arrangement for generally cooling the ware to a relatively even temperature even though the ware is moving through the lehr in multiple rows and columns. The ware is moved through the lehr on a lehr belt which is formed as a webbed belt and constitutes a foraminous conveyor. A lubricious material in the form of a vapor or mist of an organic, non-metallic coating material selected from the group consisting of polyolefins, fatty acids and their derivatives is injected into the recirculating cooling air in the cooling section of the lehr to thereby form a durable lubricious coating on the exterior surfaces of the glass article. The articles, at the time they are passed through the cooling section, will be at a temperature between 200.degree. F. and 400.degree. F.

Abstract: A thermoluminescent phosphor comprising LiF doped with boron and magnesium is produced by diffusion of boron into a conventional LiF phosphor doped with magnesium. Where the boron dopant is made to penetrate only the outer layer of the phosphor, it can be used to detect shallowly penetrating radiation such as tritium beta ays in the presence of a background of more penetrating radiation.

Abstract: An improved electroluminescent display panel having an X-Y array of display elements upon a planar insulating substrate. Integral thin film transistor circuit elements and drive signal buses are interconnected on the panel with individual electroluminescent electrodes covering a large area of the panel to increase the active display area. The electroluminescent electrode is a multilevel electrode with a first level portion disposed on the insulated substrate, a second level electrode portion disposed over an insulative polymerized layer which covers the thin film circuit areas and the drive signal buses, and a connecting electrode portion which extends between the first and second level electrode portions.

Abstract: This invention relates to light absorbing inhomogeneous films and their use in luminescent display devices such as cathode ray tubes and electroluminescent panels to achieve high contrast ratio and minimal halation effect, and more particularly to an inhomogeneous film having a composition varying continuously from metal oxide to metal, and the method of making same. The metal is selected from the group consisting of tantalum and vanadium.

Abstract: A solar cell is comprised of (1) a Cu.sub.2 S thin film evaporated on a conductive substrate at an elevated temperature thereby growing a polycrystalline film of preferred orientation, and (2) an outer CdS layer grown epitaxially on the Cu.sub.2 S film.

Abstract: A phosphor screen for converting x-rays to light includes a large number of discrete columns of the phosphor material, say doped CsI, with the spaces therebetween preferably filled with a reflective substance, which itself may be phosphor (e.g., Gd.sub.2 O.sub.2 S or La.sub.2 O.sub.2 S). Because of the resulting inhibition of lateral spread of light within the phosphor screen, it may be made thicker than conventional screens while achieving at least as high resolution and contrast, thereby increasing brightness (and thus requiring lower x-ray "doses"). A method for making the screen includes using a patterned substrate and wide-angle vapor deposition (as in a hot-wall evaporator) so as to deposit the phosphor only on the raised portions of the substrate.

Abstract: Method for depositing a luminescent film upon a substrate comprising vaporizing into a nonreactive carrier gas (1) at least one member of a first group consisting of hydrides and alkyls of M.sup.1, wherein M.sup.1 is at least one of silicon, germanium, boron, phosphorus, and aluminum, (2) at least one volatile M.sup.2 -containing organo-metallic compound of a second group, wherein M.sup.2 is at least one of zinc, cadmium, magnesium, calcium, beryllium, strontium, or barium, and (3) at least one volatile M.sup.3 -containing organo-metallic compound of a third group, wherein M.sup.3 is at least one activator for said luminescent film. The vapor-laden carrier gas and the oxidizing gas are contacted with the substrate which is at temperatures in the range of about 300.degree. to 700.degree.C. The reaction is continued unitl the desired thickness of luminescent film is achieved.

Abstract: Self-supporting luminescent screens made by applying a releasing agent to the surface of a mechanical supporting structure, having the desired shape, which agent is bound with a binding substance that is volatile at the evaporating temperature of a luminescent screen material, the latter being then deposited in a layer by evaporation onto the prepared supporting surface, until the deposited screen layer reaches a desired thickness, and eventually separating and removing the produced luminescent screen from the supporting structure.
