摘要：

The laser heated pedestal growth (LHPG) technique has been applied to grow undoped and doped Lu2SiO5:Ce3+ (LSO:Ce) single crystals fibers with stable diameter. The starting cerium concentration in the melt was [0.05-1] at.%. The thermal and growth conditions allowing pulling transparent single crystals fiber's were optimised. The fibers have been grown under N-2 + 1% O-2 atmosphere (1 bar). The Ce3+ segregation coefficient is 0.28 greater than the crystal grown by Czochralski technique. The as grown fibers demonstrated scintillating properties. (C) 2007 Elsevier B.V. All rights reserved.
