Title:
FLUORESCENT MATERIAL, FLUORESCENT MEMBER, AND LIGHT-EMITTING MODULE
Document Type and Number:
WIPO Patent Application WO/2022/168879
Kind Code:
A1
Abstract:
This fluorescent material has a garnet-type crystal structure and is represented by the general formula BaaY3-a-bAl5-aSiaO12:Ceb (where a and b satisfy 12.0113 ≤ A + 0.036b - 0.003a ≤ 12.0153 when the lattice size of the crystal structure is A, the solid solution amount of Ba is a [mol], and the solid solution amount of Ce is b [mol]).
