CERAMIC COMPOSITES FOR LIGHT CONVERSION, PROCESS FOR PRODUCTION THEREOF, AND LIGHT-EMITTING DEVICES PROVIDED WITH SAME
Provided are a ceramic composite for light conversion, which is capable of maintaining a high radiant flux even when the proportion of Gd and Ce is increased to tune the fluorescence peak wavelength to the longer wavelength side, a process for producing the ceramic composite, and a light emitting device including the ceramic composite. The ceramic composite for light conversion is a solidification product including a composition that is represented by a specific formula, and has a texture of continuously and three-dimensionally mutually entangled oxide phases including at least two phases of a first phase and a second phase, characterized in that the first phase is a Y 3 Al 5 O 12 fluorescent phase activated with Ce, and the second phase is an Al 2 O 3 phase, and the first phase and second phase account for 97% by area or more of a cross section of the solidification product, or characterized in that the first phase is a Y 3 Al 5 O 12 fluorescent phase activated with Gd and Ce, and the second phase is an Al 2 O 3 phase, and the first phase and second phase account for 97% by area or more of a cross section of the solidification product.
