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. (Y1-x-yGdxTby)AlrQ3-r(BO3)4 Formula 1 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.
