| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a fluorescent substance excellent in luminescence property at high temperatures when compared with conventional YAG fluorescent substances. <P>SOLUTION: The fluorescent substance is represented by formula [1]: Ln<SB>x</SB>(Ca<SB>(1-y-z)</SB>Sr<SB>y</SB>M<SP>II</SP><SB>z</SB>)<SB>(1-x-w)</SB>M<SP>III</SP><SB>a</SB>M<SP>IV</SP><SB>b</SB>N<SB>(c×(1-d))</SB>O<SB>(c×d)</SB>. Wherein, Ln is an activator element containing at least Ce; M<SP>II</SP>is a bivalent metal element other than Sr and Ca; M<SP>III</SP>is a trivalent metal element; M<SP>IV</SP>is a quadrivalent metal element; x satisfies 0<x≤0.5; y satisfies 0<y<1; z satisfies 0≤z<1; w satisfies 0≤w≤0.25; (a) satisfies 1≤a≤1.5; b satisfies 0.5≤b≤1; c satisfies 2.5≤c≤3.5; and d satisfies 0≤d≤0.1. <P>COPYRIGHT: (C)2008,JPO&INPIT |
