Abstract: A phosphor compliant with formula (1) below and a perovskite structure containing samarium (Sm): MTiO3: (A, B)  (1) where M is an alkali earth metal, A is an element selected from the group consisting of cerium (Ce), praseodymium (Pr), europium (Eu), terbium (Tb), and thulium (Tm), and B is a Group IIIA element of the periodic table. The phosphor has excellent luminance and lifespan while not containing S in its host matrix, and is also environmentally safe since it does not contain cadmium that is harmful to the environment. Therefore, the phosphor can be advantageously utilized for various display applications including vacuum fluorescent displays (VFDs) and field emission displays (FEDs).

The phosphor further satisfies the following formula: MTiO3:A where M is an alkaline earth metal and A is a rare earth element. The sulfur-containing phosphor shows good luminance and lifespan characteristics compared to existing SrTiO3 based phosphors, without containing cadmium that is harmful to the environment. Therefore, the phosphor is advantageously utilized for various display applications including vacuum fluorescent displays (VFDs) and field emission displays (FEDs).

Abstract: A phosphor having increased luminance and lifespan which includes a halide flux of the Group 1 element of the periodic table has a perovskite structure and satisfies the following formula: MTiO3: (A,B) where M is an alkaline earth metal, A is a rare earth element, and B is a Group 13 element of the periodic table. The halide flux-containing phosphor shows good luminance and lifespan characteristics compared to conventional phosphors without using sulfur and environmentally harmful cadmium in a host matrix. Therefore, the phosphor is advantageously utilized for various display applications including vacuum fluorescent displays (VFDs) and field emission displays (FEDs).

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.
