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:in-line-formulae description="In-line Formulae" end="lead"?(Y1-x-yGdx)Al3(BO3)4:Tby  Formula 1in-line-formulae description="In-line Formulae" end="tail"?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.
