Abstract
733,260. Electroluminescence. SYLVANIA ELECTRIC PRODUCTS, Inc. April 10, 1953 [April 12, 1952], No. 9878/53. Class 39 (1). Electroluminescent material is enclosed in a fused or sintered light-transmitting glass or ceramic and disposed between two electrodes. A metal plate 1 carries a fused layer 2 of ceramic material followed by a layer 3 of a mixture of ceramic material 5 and fine particles 4 of electroluminescent material, e.g. zinc silicate activated by manganese, calcium silicate activated by manganese and lead zinc sulphide activated by copper manganese and lead. In the latter case, a manganese salt is added to the ceramic to give a molal concentration equal to that of the manganese in the zinc sulphide to prevent the manganese passing from the luminescent material to the ceramic. A transparent conductive coating 6 is carried on layer 3. Layer 2 may be omitted. Plate 1 may be copper, steel or nickel-or copper-coated steel with good sealing and reflective properties. The ceramic material may comprise a composition or compound containing variable quantities of silica, boric anhydride, alkali metal oxide, alkaline earth oxide, aluminium oxide, phosphorus pentoxide or zinc oxide, examples being given. In the specific example, a layer of 90 per cent glass composition, 10 per cent zinc sulphide was applied by sifting on to a metal plate and heated at 700‹ C. for six minutes and the conductive coating 6 applied to this layer when cool. A neutral or reducing atmosphere may be present in the oven. The ceramic mixture may include a binder and may be applied by dipping, spraying or flowing. Additional layers of enamel or glass may be applied over or between the layers.
