Wavelength conversion particle, wavelength conversion member using same, and light emitting device
A wavelength conversion particle 7 used for a wavelength conversion member 70 is provided with a moth-eye structure section 74 having a fine concavo-convex structure in the side of a surface of a fluorescent particle 71, and the fine concavo-convex structure is formed in fluorescent particle 71 itself. Wavelength conversion member 70 is formed by dispersing wave-length conversion particle(s) 7 into a translucent medium 73 having a smaller refraction index than fluorescent particle 71 of wavelength conver-sion particle 7. Wavelength conversion member 70 is further provided with an antireflection section 76 in the side of the surface of fluorescent particle 71. Antireflection section 76 comprises moth-eye structure section 74 and translucent medium 73 entered between taper-shaped fine projections 75 of moth-eye structure section 74. In a light emitting device 1, wavelength conversion member 70 is used as a color conversion member converting a part of light emitted from a LED chip 10 into light having a longer wave-length than the light emitted from LED chip 10 and emitting the converted light.
