摘要:
Provided are a wavelength conversion member and a wavelength conversion element which are capable of reducing the decrease in luminescence intensity with time and the melting of a component material when irradiated with light of a high-power LED or LD, and a light emitting apparatus using the wavelength conversion member or the wavelength conversion element. A wavelength conversion member contains, in % by mass, 70 to 99.9% inorganic phosphor particles and 0.1 to 30% easily sinterable ceramic particles, wherein the easily sinterable ceramic particles are interposed between the inorganic phosphor particles and the inorganic phosphor particles are bound together by the easily sinterable ceramic particles.
