WAVELENGTH CONVERSION PARTICLE, WAVELENGTH CONVERSION MEMBER USING SAME, AND LIGHT EMITTING DEVICE

摘要

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 wavelength conversion particle(s) 7 into a translucent medium 73 having a smaller refraction index than fluorescent particle 71 of wavelength conversion 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 wavelength than the light emitted from LED chip 10 and emitting the converted light.
