As a light conversion member for optical devices such as white light emitting diodes, it has excellent heat resistance, durability, etc., easy adjustment of the ratio of light and fluorescence of the light source, can reduce color unevenness and variation of the emitted light, and high internal It is an object of the present invention to provide a ceramic composite material for light conversion having quantum efficiency and fluorescence intensity, a manufacturing method thereof, and a light-emitting device having high light conversion efficiency provided with the ceramic composite material. A ceramic composite material for light conversion composed of a fluorescent phase and a translucent phase, wherein the fluorescent phase is Ln 3 Al 5 O 12 : Ce (Ln is at least one element selected from Y, Lu and Tb) And Ce is an activation element.), And the light transmitting phase is a phase containing LaAl 11 O 18 . |
