Title:
A wavelength control optical member, a luminescent device, and a light
Document Type and Number:
Japanese Patent JP6213938
Kind Code:
B2
Abstract:
This wavelength controlling optical member is provided with a matrix resin (1) and dye-containing fine particles (2) that are dispersed in the matrix resin. The dye-containing fine particles contain a dye (3) that has a maximum absorption wavelength within the range of from 400 nm to 650 nm, a singlet oxygen quencher (4), an antioxidant (5) and an ultraviolet absorbent (6). A light emitting device and a lighting apparatus according to the present invention comprise a light emitting element, a wavelength conversion member that converts the wavelength of light emitted from the light emitting element, and a wavelength controlling optical member.
