    • PROBLEM TO BE SOLVED: To provide a phosphor having a broad fluorescent spectrum corresponding to all of RGB three primary colors in a visible light region from 400 nm to 700 nm and preventing delay in a relaxation time.
      SOLUTION: An electrodialysis device 1 is constituted by alternately arranging a plurality of cation exchange membranes 14 and a plurality of anion exchange membranes 15 between an anode 11 and a cathode 12 to alternately form desalination chambers 17 and concentration chambers 16. An aqueous solution of zinc sulfate is introduced into the desalination chamber 17a while an aqueous solution of sodium hydroxide is introduced into the desalination chamber 17b; at least one kind of additive among aluminum, gallium, indium, lithium and sodium is introduced into the first desalination chamber 17a; a voltage is applied to the anode 11 and the cathode 12 to allow zinc ions from the desalination chamber 17a and hydroxyl ions from the desalination chamber 17a to move to the concentration chamber 16; and fine particles of zinc oxide are produced based on the zinc hydroxide produced in the concentration chamber 16.

    • 要解决的问题:提供一种具有对应于400nm至700nm的可见光区域中的所有RGB三原色的宽荧光光谱并防止弛豫时间延迟的荧光体。 解决方案:电渗析装置1通过在阳极11和阴极12之间交替排列多个阳离子交换膜14和多个阴离子交换膜15而交替地形成脱盐室17和浓缩室16。 将硫酸锌溶液引入脱盐室17a中,同时将氢氧化钠水溶液引入脱盐室17b中; 将铝,镓,铟,锂和钠中的至少一种添加剂引入到第一脱盐室17a中; 向阳极11和阴极12施加电压,以允许来自淡化室17a的锌离子和来自淡化室17a的羟基离子移动到浓缩室16; 并且基于在浓缩室16中产生的氢氧化锌生产氧化锌的细颗粒。版权所有(C)2009,JPO&INPIT
