Lutetium-aluminum-garnet sintered body containing praseodymium and method for producing the same

摘要

PROBLEM TO BE SOLVED: To provide a Pr:LuAG sintered body which has a level of linear transmittance equivalent to that of a Pr:LuAG single crystal, which can be obtained by not adding Si as a sintering aid, and is excellent in light emission amount and uniformity. Provided is a Pr:LuAG sintered body suitable for a scintillator material for detecting gamma rays and a method for producing the same. SOLUTION: Lu
