RARE EARTH ALUMINATE SINTERED BODY AND METHOD FOR PRODUCING THE SAME
To provide a rare earth aluminate sintered body having a high light extraction efficiency, and a method for producing the same.SOLUTION: A rare earth aluminate sintered body includes crystal agglomerated particles containing a rare earth aluminate fluorescent material crystal phase, and a rare earth aluminate crystal phase having a refractive index different from that of the rare earth aluminate fluorescent material crystal phase. The rare earth aluminate crystal phase is arranged around the crystal agglomerated particles.SELECTED DRAWING: Figure 5
