Ceramic Composite Material for Optical Conversion, Production Method Therefor, and Light-Emitting Device Provided with Same
An objective of the present invention is to provide a ceramic composite material for light conversion which exhibit s excellent heat resistance, durability, and the like as a light converting member of an optical device such as a white light emitting diode, easily controls the ratio of light from a light source and fluorescence, can reduce color unevenness and variance of emitted light, and has high internal quantum efficiency and fluorescence intensity, a method for producing the same, and a light emitting device which includes the same and has high light conversion efficiency. Provided is a ceramic composite material for light conversion including: a fluorescence phase; and a light transmitting phase, the fluorescence phase being a phase containing Ln3Al5O12:Ce (Ln is at least one element selected from Y, Lu, and Tb, and Ce is an activation element), and the light transmitting phase being a phase containing LaAl11O18.
