Method for manufacturing wavelength converting member
The present invention relates to a method for manufacturing the wavelength converting member comprising a polycrystalline sintered ceramic comprising (A) a garnet phase having the compositional formula (1): (A 1-x B) 3 C 5 O 12 (1) wherein A is at least one rare earth element selected from the group consisting of Y, Gd, and Lu, B is at least one rare earth element selected from the group consisting of Ce, Nd, and Tb, C is at least one element selected from the group consisting of Al and Ga, and x is a number from 0.002 to 0.2, and (B) at least one phase selected from the group consisting of perovskite, monoclinic and silicate phases, fine grains of phase (B) being included in a matrix of crystal of phase (A) and dispersed in a matrix of crystal of phase (A), wherein method comprises the steps of mixing a first source powder comprising the elements contained in phase (A) in such a composition as to form phase (A), with a second source powder comprising the elements contained in phase (B) in such a composition as to form phase (B), shaping the powder mixture into a formed body, and heating the body for sintering.
