A thin-film electroluminescent device includes dielectric layers having improved dielectric characteristics. The device is fabricated by forming a first transparent electrode layer of ITO, a first dielectric layer, a luminescent layer, a second dielectric layer, and a second transparent electrode layer of ITO in this order on an insulating substrate. Each of the two dielectric layers is a film constituted by TaSnON. That is, the film includes tantalum, tin, oxygen, and nitrogen.
Abstract:
A construction for electroluminescent device includes a substrate and an electroluminescent stack which forms a step relative to the substrate. A transparent layer of protective material is placed atop the stack to bridge the step and create a smooth edge profile along the edge. A metallization layer is situated atop the layer of protective material and is coupled to the electroluminescent stack through vias in the protective material.
Abstract:
A flexible, thick film, electroluminescent lamp and method of construction in which a single non-hygroscopic binder is used for all layers (with the optional exception of the rear electrode), thereby reducing delamination as a result of temperature changes and the susceptibility to moisture. The binder includes a fluoropolymer resin, namely polyvinylidene fluoride, which has ultraviolet radiation absorbing characteristics. The use of a common binder for both phosphor and adjacent dielectric layers reduces lamp failure due to localized heating, thus increasing light output for a given voltage and excitation frequency, and increasing the ability of the lamp to withstand overvoltage conditions without failure. The lamps may be made by screen printing, by spraying, by roller coating or vacuum deposition, although screen printing is preferred. By the multilayer process, unique control of the illumination is achieved.
Abstract:
A phosphor particle having a non-particulate, conformal aluminum oxide coating and a fluorescent lamp incorporating aluminum oxide coated phosphor particles are disclosed. A method for improving the lumen maintenance of a fluorescent lamp is also disclosed. The method involves applying a non-particulate, conformal aluminum oxide coating to the outer surface of individual particles of a finely-divided fluorescent lamp phosphor, applying the coated phosphor particles to a fluorescent lamp envelope, and processing the phosphor coated envelope into a finished lamp.
Abstract:
In a low-pressure mercury vapor discharge lamp a method of applying a tin oxide coating to the inside wall of the lamp having a resistance per square of more than 10,000 Ohm to avoid blackening of the glass. This coating may be used in the aperture of a lamp for photo-copying purposes.
