摘要： α-sialon phosphor that is α-sialon represented by a general expression: (M)x(Eu)y(Si, Al)12(O, N)16 (where M is one or more types of elements selected from a group consisting of Li, Mg, Ca, and Y as well as lanthanide element (except for La and Ce) and including at least Ca), the α-sialon phosphor being structured so that an oxygen content is 1.2 mass % or less and primary particles constituting the α-sialon have a columnar shape. When the α-sialon phosphor receives ultraviolet rays or visible light having a wavelength from 250 to 500 nm as an excitation source, the α-sialon phosphor shows a fluorescent characteristic having a peak in a wavelength region from 595 to 630 nm.

摘要： A fluorescent material comprising: a β-Sialon expressed by the general formula Si6-ZAlZOZN8-Z as a host material; and Eu dissolved in solid solution as a luminescence center, is a powder which, when measured by the laser diffraction scattering method, gives particle diameter distribution in which cumulative 10% diameter (D10) falls within the 7 μm to 20 μm range and 90% diameter (D90) within the 50 μm to 90 μm range, and can be used as a fluorescent material low in luminescence intensity degradation ideal for illuminators. This fluorescent material can be produced by subjecting a raw powder, which is obtained by mixing a silicon nitride powder, aluminum nitride powder, and aluminum-containing or Eu-containing compound as required, to heating at 1850° C. to 2050° C. for 9 hours or longer in a nitrogen or nonoxidizing atmosphere.
