WAVELENGTH CONVERSION MEMBER AND LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a wavelength conversion member which is small in the decrease in light emission intensity with time when exposed to light of an LED or LD is applied.SOLUTION: A wavelength conversion member comprises: a sintered compact of a powder mixture of (a) glass powder including, as a glass composition, an alkali metal element and at least one element selected from Sn and Fe and (b) inorganic phosphor powder.SELECTED DRAWING: Figure 1
