Abstract : Methods of applying electrically conducting coatings of copper selenide and coatings with a composition of Cu3PSx to organic glass and transparent polymer ribbons are discussed. Copper selenide coatings are produced by vacuum deposition of Cu2Se. Heating the object afterwards at 70-80C for 30-60 min improves transparency and electrical conductivity. A coating of Cu3PSx is formed by vacuum vaporization of phosphorus powder, which was first fused onto tungsten or tantalum ribbons. Afterwords it is necessary to work the substance in sulfur vapor to increase the transparency and stability of the coating. Transmission characteristics of this coating are similar to those of the Cu2Se coating. A detailed explanation is given of the methods used to manufacture specimens of electroluminescent capacitors with these coatings on organic glass. All steps of the process, including deposition of the coating, protective coatings, adhesion of the electrical contacts and hermetic sealing, are presented.
