<P>PROBLEM TO BE SOLVED: To provide a green light-emitting phosphor whose light-emitting peak is broad. <P>SOLUTION: This green light-emitting phosphor of the present invention comprises calcium (Ca), magnesium (Mg), silicon dioxide, an activating agent, and a halogen. At least one of strontium (Sr) and barium (Ba) may further be contained. The green light-emitting phosphor of the present invention may be represented by general formula: (Ca<SB>a</SB>, Sr<SB>b</SB>, Ba<SB>c</SB>, Eu<SB>d</SB>)<SB>8</SB>Mg<SB>1-x</SB>Mn<SB>x</SB>Si<SB>4</SB>O<SB>16</SB>Cl<SB>2</SB>(wherein, 0<a<1.0, 0≤b<0.5, 0≤c<0.5, 0<d<0.2, a+b+c+d=1.0, 0≤x<0.3). <P>COPYRIGHT: (C)2009,JPO&INPIT |
