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.

Abstract: Hybrid composites including carbon nanotubes and a carbide-derived carbon material, electron emitters including the hybrid composites, methods of preparing the electron emitters, and electron emission devices including the electron emitters are provided. Specifically, a hybrid composite includes at least one carbon nanotube and a carbide-derived carbon material. The carbide-derived carbon material is prepared by thermochemically reacting a carbide compound with a halogen-containing gas to extract substantially all of the elements except for the carbon in the carbide compound. Since the carbon nanotubes and the carbide-derived carbon material are hybridized and composited, a screen effect that may occur when large amounts of carbon nanotubes are used can be prevented, and an electron emitter including the hybrid composite has excellent electron emission capabilities, excellent uniformity, and a long lifetime.
