  • Metal oxide coated phosphor for plasma display panel and manufacturing method thereof
    Publication number: 20060210791
    Abstract: The present invention relates to a phosphor for a plasma display panel and a method for producing the same. The phosphor is formed by coating a metallic oxide having a high polarity to a surface of a green phosphor Zn2SiO4:Mn with a thickness 10 nm to 0.5 ?m. The concentration of a metallic oxide is in a range of 1 to 50 weight % with respect to the green phosphor. According to the green phosphor for the plasma display panel of the present invention, which is made with coating, a metallic oxide having a positive polarity to a surface of a phosphor can be adjusted, thereby enhancing the discharge characteristics when the panel is driven.
