  • Publication number: 20130094186
    Abstract: The present invention aims to provide a surface-treated phosphor having high dispersibility and capable of significantly enhancing moisture resistance without deteriorating the fluorescence properties, and a method for producing the surface-treated phosphor. The surface-treated phosphor includes: a phosphor body; and a surface treatment layer containing at least one specific element selected from elements of the third to sixth groups of the periodic table, and fluorine, the phosphor body having the surface treatment layer on the surface thereof, wherein, when a cross section of the surface treatment layer is subjected to a thickness-wise elemental distribution analysis by a combination of an electron microscopic analysis and an energy-dispersive X-ray element analysis, a peak indicating the maximum content of the specific element appears nearer to the surface than a peak indicating the maximum fluorine content.

  • Patent number: 8147783
    Abstract: Disclosed are a nickel hydroxide powder and a method for producing the same. The nickel hydroxide powder comprises a particle in the form of sphere, an average particle diameter of 0.1 ?m or more and 30 ?m or less, and the amount of the particles having a diameter of 0.7 times or more and 1.3 times or less the average particle diameter of 80% by weight or more based on the total amount of particles. The method for producing a nickel hydroxide powder comprises the steps of (1) to (4): (1) injecting a solution containing a nickel salt through a pore into a liquid mutually insoluble with the solution to obtain an emulsion including solution as a dispersed phase and the liquid as a continuous phase; (2) gelating the emulsion; (3) separating the dispersed phase from the obtained gel to obtain a cake; and (4) drying the cake.
