  • Luminous material for scintillator comprising single crystal of Yb mixed crystal oxide
    Patent number: 7347956
    Abstract: Disclosed is a luminescent material for scintillators, which comprises a single crystal of an Yb-containing mixed-crystal oxide having a base crystal consisting of a garnet single crystal or a borate single crystal. The oxide single crystal has a composition represented by either one selected from the group consisting of R3Al5O12, R3Ga5O12, Li6R(BO3)3, LaR2Ga3O12 and Gd3R2Ga3O12, wherein R is a mixture of Yb and either one of Y, Gd and Lu. The Yb as an element capable of forming an optically active state called CTS together with a neighboring negative ion (oxygen ion).
