    摘要: A light-emitting device and illumination apparatus using the same are provided. The light-emitting device includes a semiconductor light-emitting element that emits blue-violet or blue light and a fluorescent material that absorbs the light emitted by the semiconductor light-emitting element and emits fluorescence of wavelengths different from the light, wherein the fluorescent material includes a mixture of a first fluorescent material, a second fluorescent material that has a longer emission wavelength than that of the first fluorescent material, and a third fluorescent material that has a longer emission wavelength than the second fluorescent material, and the first fluorescent material is a europium-activated β-SiAlON fluorescent material, the second fluorescent material is a europium-activated α-SiAlON fluorescent material, and the third fluorescent material is a nitride crystalline red fluorescent material of a general formula of (Ca,Eu)AlSiN3. The illumination apparatus includes a light source including a light emitting device as described above.

    摘要: A method for producing cubic boron nitride includes maintaining hexagonal boron nitride in the presence of a catalyst substance under conditions where cubic boron nitride remains thermodynamically stable to thereby transform hexagonal boron nitride into cubic boron nitride, wherein the catalyst substance contains LiMBN2, in which M represents Ca, Sr, Ba, Ra, Be, or Mg, and at least one species selected from the group consisting of alkali metals, alkaline earth metals, nitrides thereof and boronitrides thereof. Any one of the LiMBN2, alkali metals, alkaline earth metals, nitrides thereof and boronitrides thereof has an oxygen content of 1% or less. As a result, the percent transformation into cubic boron nitride can be considerably enhanced, and the cubic boron nitride obtained exhibits high mechanical strength.
