Crystalline silicon nitride and a manufacturing method thereof, as well as, a phosphor using the same, phosphor-containing composition, a light-emitting device, the illumination device, an image display device, a sintered body and a pigment

摘要

PROBLEM TO BE SOLVED: To provide: silicon nitride having high whiteness and reflectance; a method for producing the same; a phosphor having clear object color and high luminous brightness in comparison with a conventional one; a phosphor-containing composition; a light emitting device using the phosphor; an illuminating device; an image display; a ceramic having high whiteness; and a pigment.;SOLUTION: As a raw material of the phosphor, crystalline silicon nitride, having a crystal phase and exhibiting reflectance of 85% when it is irradiated with a light having a wavelength of 525 nm, is used.;COPYRIGHT: (C)2010,JPO&INPIT
