Abstract: A dense cathode electrode layer having a step coverage is to be formed on an electron injection layer. The electron injection layer in which fine particles of an electron injection material is dispersed in an organic thin film having an electron transport property is formed by vapor co-depositing the electron transport material and the electron injection material; and a cathode electrode layer made of an alloy layer of MgAg is formed by a sputtering method. Since lower portions of the fine particles of the electron injection material dispersed in the surface of the organic thin film are buried in the organic thin film, the electron injection particles are not peeled off even if sputtering particles collide with the electron injection particles, and the upper portions are in contact with the cathode electrode layer formed by sputtering particles.

Due to the reduction process holders (22) with different mercury contents have a different color.

Abstract: A method for manufacturing a thin-film EL device utilizes a Zn-Mn target that contains less Mn than the optimum Mn concentration on the basis of the finding that the light-emitting layer grown by the sputtering method contains more Mn than in the target. Manganese concentration on the target surface layer is controlled by changing the area ratio between ZnS and Mn exposed on the surface of the target. Manganese concentration on the target surface is controlled at preferably from 0.3 to 0.4 wt % when the target surface is sulfurized during sputtering and less than 0.1 wt % when the target surface is not sulfurized.

Abstract: A method is provided for making a lithium-sodium-antimony photocathode including the step of forming a base layer including antimony on a substrate. Sodium is then deposited onto the base layer at an elevated temperature to a first peak value of responsivity, thereby forming a sodium-antimony surface. Next, at room temperature, lithium is deposited onto the substrate containing the sodium-antimony surface until the lithium-sodium-antimony photocathode develops a hazy brown color. The photocathode is sensitized by heating the substrate to an elevated temperature until a second peak value of responsivity, greater than the first peak value, is obtained. Antimony, sodium and lithium are then alternately deposited on the photocathode in order to stabilize the second responsivity peak.
