Abstract

778,907. Electroluminescence. SYLVANIA ELECTRIC PRODUCTS, Inc. Aug. 20, 1953 [Aug 20, 1952], No. 32476/56. Divided out of 778,905. Drawings to Specification. Class 39(1). Electroluminescent material is mixed with up to 10 per cent of particles of metal. Some of the particles of metal may be coatings on the phosphor particles. The metal may be evaporated as a thin film onto a compressed layer of electroluminescent material, and ball milling the layer. The remaining subject-matter is as described in Specification 778,905.
