Abstract: PURPOSE: An europium oxynitride phosphor is provided to selectively use the phosphor, and to prevent the reduction of the brightness of the phosphor when being exposed to air or an excitation source. CONSTITUTION: An europium oxynitride phosphor irradiates lights by activating a mother body marked with chemical formula 1: (Eu_(1-a-b-d)A_aB_bD_d)E_eO_xN_z. In the chemical formula 1, A is one or two elements selected from the group consisting of Lanthanum group metal elements. B is one or two elements selected from the group consisting of divalent metal elements. D is one or two elements selected from the group consisting of trivalent metal elements. E is one or two elements selected from the group consisting of tetravalent metal elements.

Abstract: A strontium magnesium silicate-based white phosphor is provided to ensure excellent light emitting property in a condition excluding a fluxing agent for lowering temperature and a poison component, and high efficiency. A method for manufacturing strontium magnesium silicate-based white phosphor comprises the steps of: mixing a strontium precursor, barium precursor, calcium precursor, magnesium precursor, silica precursor and europium precursor in the content represented by formula 1: (3-x-y)SrO.x(aBaO.bCaO).MgO.Si_zO_8 : yEu^(2+); drying the mixture at 100~150 °C to manufacture a phosphor precursor; and heat-treating the precursors in a mixed gas atmosphere of rogen and hydrogen at 800~1500 °C. In the chemical formula 1, 0
