OXYNITRIDE-BASED PHOSPHOR CAPABLE OF EMITTING VARIOUS COLOR FROM GREEN COLOR TO YELLOW COLOR WHEN COMPRISING BLUE LIGHT EMITTING DIODE OR UV LIGHT EMITTING DIODE AS AN EXCITATION SOURCE
PURPOSE: An oxynitride-based phosphor is provided to have excellent stability under environment comprising moisture or under oxidation atmosphere because of excellent structural stability, and to have excellent light efficiency at Eu doping.;CONSTITUTION: An oxynitride-based phosphor comprises a base material having monoclinic crystal structure represented by chemical formula: (Ca_(1-x) M1_x)_a(La_(1-y) M2_y)_bSi_cN_dO_e, and one or more kinds as a luminous center metal atom selected from Mn, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Tb, Ho, Er, Tm, Yb solved in the base material. In the chemical formula, 1=a=30, 0.3a=b=1.7a, 1.5(a+b)=c=3(a+b), 1.2c=d=1.5c, 0.8(a+1.5b)=e=1.2(a+1.5b), 0=x=0.5, 0=y=0.5, M1 is an element of one or more selected from Ba, Mg, Sr and Zn, M2 is one or more selected from Y, Lu, Sc, Gd, Tb and Ce.;COPYRIGHT KIPO 2013
