ABSTRACT:
Provided are a phosphor used in a PDP, which is a compound represented by Formula 1 below and a PDP including a phosphor layer comprising the phosphor.in-line-formulae description="In-line Formulae" end="lead"?(Y1-x-yGdxTby)AlrQ3-r(BO3)4  Formula 1in-line-formulae description="In-line Formulae" end="tail"?where 0<x≦1, 0<y≦1, Q is Sc, In, or Ga, and 0≦r<3.When the phosphor is used to form a green phosphor layer of a PDP, the luminance saturation problem of a conventional green phosphor can be overcome. In addition, a PDP including a phosphor layer comprising the phosphor has a wider color reproduction range and no reduction in luminance according to the mixing ratio of each phosphor contained in the phosphor compared with a conventional phosphor used in a PDP. Therefore, a PDP including a phosphor layer comprising the phosphor can have far superior image qualities.
