RARE EARTH SILICATE SINGLE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To provide a rare earth silicate single crystal which makes it possible to decrease slow components of a photogenesis decay curve required in scintillator characteristics and to shorten the time for fluorescence decay. SOLUTION: The rare earth silicate single crystal contains Fe of 0.1 ppm or over and≤50 ppm. The rare earth component of the rare earth silicate single crystal is gadolinium. The rare earth silicate single crystal is cerium activated gadolinium silicate. COPYRIGHT: (C)2004,JPO
