LIGHT EMITTING COMPOSITION AND LIGHT SOURCE APPARATUS |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a light-emitting composition which is improved in the excitation efficiency by a blue color region light is attempted. <P>SOLUTION: The light-emitting composition comprises a fluorescent material shown by a general formula described as Sr<SB>x</SB>Ba<SB>2-x</SB>SiO<SB>4</SB>:Eu and a magnesium salt to be added to the fluorescent material and has a value of (intensity at a wavelength of 440 nm/intensity at a wavelength of 360 nm) on an excitation spectrum of ≥0.82 and ≤0.85. <P>COPYRIGHT: (C)2007,JPO&INPIT |
