Abstract: A phosphor for a plasma display panel (PDP) has a decay time of about 1 ms or less when a Xe concentration is about 10 wt % to about 30 wt % based on the total weight of a discharge gas. A phosphor composition includes the same and a PDP includes a phosphor layer comprising the phosphor or the phosphor composition. When the phosphor or the phosphor composition are used, a low gray scale and low discharge problem due to a green phosphor of a PDP may be solved, a permanent afterimage due to a green phosphor is reduced, and a color reproduction range is significantly broadened compared to a conventional green phosphor of a PDP. In addition, the circuit of the PDP is simplified since colors are not individually subjected to gamma correction but are corrected using a single white gamma. Furthermore, the contrast in a light room is also improved due to the use of phosphor powders with color.

Abstract: Disclosed is a low-voltage blue color fluorescent substance which is doped with 0.5 to 3 weight % of P, and a manufacturing method of the same. The above blue color fluorescent substance is manufactured by mixing phosphoric compound as flux with a mixture of zinc oxide (ZnO) and gallium oxide (Ga2O3); carrying out a primary burn on the mixture at a temperature of 1,200 to 1,300° C.; ball milling and washing; and carrying out a secondary burn on the resultant material at a temperature of 900 to 1,100° C., and then classifying the substance.

Abstract: A low-voltage excited blue phosphor is provided. The phosphor comprises a matrix represented by general formula ZnO.Ga2O3, and Bi doped in the matrix. To prepare the phosphor, ZnO, Ga2O3, Bi compound, and a flux are mixed to produce a mixture, and the mixture is fired at 1100-1300° C. to produce a fired material. Then the fired material is milled, and washed with an acid. The washed material is fired at 800-1100° C. and sieved to produce the blue phosphor.

Abstract: Disclosed is a low voltage blue emitting phosphor and a method for producing the same including the steps of: mixing ZnO, Ga2O3and a Na-based compound to obtain a mixture material; sintering the material at a temperature of 1100 to 1300° C.; milling the first sintered material; washing the milled material using hydrochloric acid; sintering the washed material at a temperature of 800 to 1100° C.; and classifing the material. The low voltage blue emitting phosphor produced as described above is a ZnO—Ga2O3matrix doped with Na, and has an x value of 0.18±0.05 and a y value of 0.17±0.05 in a CIE chromaticity diagram.

Abstract: An improved red, green or blue phosphor complex produced by adhering chromium compound on the red, green or blue phosphor using a polymer binder or an inorganic binder, or without a binder, has high brightness without changing the characteristics of the phosphor
