A light-emitting ceramic based panel, hereafter termed 'electroceramescent' panel, is herein claimed. The electroceramescent panel is formed on a substrate providing mechanical support as well as serving as the base electrode for the device. One or more semiconductive ceramic layers directly overlay the substrate, and electrical conductivity and ionic diffusion are controlled. Light emitting regions overlay the semiconductive ceramic layers, and said regions consist sequentially of a layer of a ceramic insulation layer and an electroluminescent layer, comprised of doped phosphors or the equivalent. One or more conductive top electrode layers having optically transmissive areas overlay the light emitting regions, and a multi-layered top barrier cover comprising one or more optically transmissive non-combustible insulation layers overlay said top electrode regions.

Light emitting ceramic device and method for fabricating the same

This invention relates to enhanced selectivity anion membrane electrodes useful in determining the amount of an anion of interest in a biological sample. The enhanced selectivity anion membrane formulation contains fumed silica, a polymer material, and an anion selective agent. The presence of fumed silica surprisingly minimizes or reduces the effect of interfering substances, such as salicylate which may be present in biological samples and which interfere with the determination of various anions of interest, such as chloride (Cl.sup.31).

Anion selective electrodes containing fumed silica

A thick film low-end resistor composition comprising an admixture of finely divided particles of (a) silver, palladium, an alloy of palladium and silver, or mixtures thereof; (b) an admixture of (1) glass having a softening point of 350.degree. to 500.degree. C., which when molten is wetting with respect to the other solids in the composition, and (2) glass having a softening point of 550.degree. to 650.degree. C.; and (c) 5-20% by volume, basis total solids, of sub-micron particles of RuO.sub.2, all of (a) through (c) being dispersed in (d) an organic medium.
