NITRIDE PHOSPHOR, PROCESS FOR PRODUCING NITRIDE PHOSPHOR AND WHITE LIGHT-EMITTING ELEMENT |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a nitride phosphor that has an emission peak wavelength in a range of 600 nm or more, more specifically in a range of 620-650 nm and a high luminous intensity, to provide a process for producing the nitride phosphor and to provide a white light-emitting element. <P>SOLUTION: The nitride phosphor has a chemical composition represented by the formula (1) as shown below and has a peak emission wavelength in a range of 600-650 nm. Formula (1) is (Ca<SB>x</SB>Sr<SB>y</SB>Eu<SB>z</SB>)<SB>m/2</SB>Si<SB>12-(m+n)</SB>Al<SB>m+n</SB>O<SB>n</SB>N<SB>16-n</SB>wherein x+y+z=1; 0<y/(x+y)≤1; 0<z≤0.3; 0.6<m<3.0; and 0≤n≤1.5. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
