<P>PROBLEM TO BE SOLVED: To provide a single crystal for a scintillator, which can be suitably applied to a radiation detector and has a short fluorescence lifetime. <P>SOLUTION: The garnet type single crystal for a scintillator is expressed by a general formula (1): Gd<SB POS="POST">3-x-y</SB>Ce<SB POS="POST">x</SB>RE<SB POS="POST">y</SB>Al<SB POS="POST">5-Z</SB>M<SB POS="POST">z</SB>O<SB POS="POST">12</SB>(1) (In the formula (1), 0.0001≤x≤0.15, 0.6≤y≤3, 0≤z≤4.5, M is at least one type selected from Ga and Sc, and RE is at least one selected from Yb and Lu) and has a fluorescent component of which fluorescence lifetime is 100 nano-second or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
