METHOD FOR PRODUCING LIGHT WAVELENGTH CONVERSION MEMBER, LIGHT WAVELENGTH CONVERSION MEMBER, LIGHT WAVELENGTH CONVERSION COMPONENT AND LIGHT EMITTING DEVICE
To provide a method for producing an optical wavelength conversion member, the method being capable of reducing blackening of the optical wavelength conversion member; an optical wavelength conversion member with suppressed blackening; an optical wavelength conversion component including the optical wavelength conversion member; and a light-emitting device including the optical wavelength conversion member or the optical wavelength conversion component. Provided is a method for producing an optical wavelength conversion member 9 composed of a sintered body containing, as main components, AlOand a component represented by formula ABO:Ce. The production method involves firing in a firing atmosphere having a pressure of 10Pa or more and an oxygen concentration of 0.8 vol.% or more and less than 25 vol.%. Thus, the blackening of the sintered body is prevented in a furnace atmosphere, and the sintered body exhibits superior fluorescent properties. The optical wavelength conversion member 9 produced by the production method exhibits high fluorescence intensity and achieves high color uniformity. Thus, the production method can produce the optical wavelength conversion member 9 exhibiting superior fluorescent properties in the presence of a high-output LED or laser light source.
