  • Publication number: 20110127466
    Abstract: A green phosphor including a compound represented by Formula 1 (Y3-xMx) (Al5-yM?y)O12:Cez and a pigment. The green phosphor having the compound represented by Formula 1 and a pigment has a shorter decay time than conventional phosphors, and thereby confers excellent luminescence characteristics and color purity. A display panel including the green phosphor 1 is also provided herein.

  • Patent number: 7919922
    Abstract: Provided are a green phosphor for a plasma display panel (PDP) represented by Formula 1 and a PDP including a phosphor layer formed of the same: (Y1-x-yGdx)Al3(BO3)4:Tby??Formula 1 where 0?x<1, 0<y<1 and 0<x+y<1. The luminance saturation characteristic of a green phosphor layer can be improved using the green phosphor for a PDP according to the present embodiments, and the green phosphor can also be mixed with conventionally used green phosphors. Image quality can be improved according to a mixing rate of the green phosphor and conventionally used green phosphors since color reproduction range widens and luminance does not decrease compared to using the conventional green phosphors.
