    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.
