METHOD OF MANUFACTURING WAVELENGTH CONVERSION MEMBER, WAVELENGTH CONVERSION MEMBER, AND LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a wavelength conversion member capable of emitting high-intensity fluorescence.SOLUTION: A raw ceramic element body 3 containing a glass powder and an inorganic phosphor powder 12 is prepared. A firing step of firing the raw ceramic element body 3 to obtain a wavelength conversion member 1 including a glass matrix 11 and the inorganic phosphor powder 12 arranged in the glass matrix 11 is performed. In the firing step, the raw ceramic element body 3 is heated to a temperature at which the viscosity of glass is 10dPa s or less.
