Abstract: Provided is a green phosphor for a plasma display panel (PDP) represented by Formula 1. (Cax,Mgy,Zn2-x-y)SiO4:Mn??Formula 1 Here, 0<x, y<1. The green phosphor is used alone or in combination with BaMgAlqOz:Mn (7<q<15 and 12<z<28) to prepare a phosphor layer, and a PDP including a phosphor layer formed of the green phosphor may have improved luminance deterioration property.

Abstract: A plasma display panel including a pair of substrates comprises a mixture of discharge gases contained between the substrates; the mixture consists of neon gas, xenon gas and krypton gas, wherein a percentage content of the krypton gas is selected in the range from 1 to 14 percent of the mixture, whereby near-infrared rays radiated from the xenon gas during the gas discharge is retarded while the operational margin of the AC driving voltage is preferably maintained.

Abstract: There is disclosed an apparatus for forming a fluorescent layer in a plasma display panel by applying a fluorescent paste into grooves formed between a plurality of ribs disposed in parallel on a surface of a substrate. The apparatus includes: a platform for mounting the substrate thereon; a dispenser having at least one nozzle for ejecting the fluorescent paste; a transporter for moving the nozzle relative to the platform; and a controller for controlling the transporter and the dispenser so that the fluorescent paste is consecutively applied into the predetermined grooves between the ribs.
