Abstract
1,129,832. Electroluminescence. GENERAL TELEPHONE & ELECTRONICS LABORATORIES Inc. 12 Oct., 1965 [12 Oct., 1964], No. 43335/65. Heading C4S. [Also in Division C7] A method for the preparation of an electroluminescent film (e.g. 1 to 2 microns thick) comprises placing a substrate (e.g. glass) having a conductive coating in an evacuated chamber, depositing a mixture of zinc sulphide with activator (e.g. chlorine from 0À01 to 0À10 weight per cent) and manganese sulphide (e.g. 5 to 15 weight per cent manganese based on the zinc sulphide), depositing copper on the film (e.g. 1 weight per cent of the zinc sulphide), heating the substrate to 500‹ to 700‹ C. for example to crystallize the film and diffuse the deposited copper into the film and thereafter cooling the substrate. The preparation may be in a chamber wherein the different materials are mounted on a disc which is colated to place them sequentially under the substrate, each material being vaporized by a separate heater. The film thickness may be monitored by interference pattern techniques.
