    摘要: An improved fine grained zinc sulfide phosphor is provided for use in ac electroluminescent displays. The fine-grained zinc sulfide phosphor film exhibits improved luminance and may be used in conjunction with a structure or substance to minimize or prevent reaction of the fine grained phosphor with oxygen. The invention is particularly applicable to zinc sulfide phosphors used in electroluminescent displays that employ thick dielectric layers subject to high processing temperatures to form and activate the phosphor films.

    摘要: A novel sub-structure of a thick film dielectric electroluminescent display and a thick film dielectric electroluminescent display incorporating the same is provided. The sub-structure comprises a barrier layer between a substrate and a thick film dielectric layer. The barrier layer is chemically inert with respect to the substrate and the thick film dielectric layer and the barrier layer inhibits diffusion of at least one chemical species therethrough. This sub-structure results in a higher capacitance for the thick dielectric layer, which provides higher display luminance and a reduced tendency for dielectric breakdown of the thick dielectric layer. The barrier layer permits for lower cost substrates, such as glass, to be used.

    摘要: A process for producing an electroluminescence element provided with a luminescent layer sandwiched between two electrodes on an insulating substrate, the luminescent layer being composed of a host material with a luminescent center element added. The process comprises a step of forming the aforesaid luminescent layer as a film onto the insulating substrate by either sputtering or evaporation, by use of a source material composed of a compound of an element of Group II and an element of Group VI, to which a halide of a rare earth element is added as the luminescent center element. The atmosphere at the time of the film formation contains either a halogen gas or halide gas. The aforesaid luminescent layer is formed as a film onto the insulating substrate by either sputtering or evaporation, by use of a source material composed of the aforesaid compound of an element of Group II and an element of Group VI, to which a fluoride or fluorine compound of the luminescent center element and a halide other than fluoride of the element of Group II are added. The film formation atmosphere may be pretreated with a chlorine-containing gas prior to a film formation step of forming the luminescent layer as a film onto the insulating substrate by a sputtering method by use of a source material composed of the host material with the luminescent center element. An electro-luminescence element is further disclosed, wherein the X-ray diffraction spectrum thereof has only a single peak at an X-ray diffraction angle from the luminescent layer, ranging from 25.degree. to 30.degree. according to a thin film X-ray diffraction measuring method using Cu-Kd radiation, and no other peaks of the X-ray diffraction spectrum exist at an X-ray diffraction angle of approximately 27.degree..
