چکیده
Scintillation single crystal fibers (SCFs) have great potential applications in the new generation of high-energy ray and particle detectors due to their morphological advantages. In this work; Ce:LuAG SCFs with a diameter 1 mm were grown along direction [111] by laser-heated pedestal growth (LHPG) method using transparent ceramic as source rod; doping concentration was 0.1 at%, 0.3 respectively. The effects rate annealing air on scintillation optical properties SCF are discussed detail. results analyzing absorption spectra; radioluminescence (RL) pulse-height spectra fluorescence lifetime show that maintains excellent performance while having fiber structure. Therefore; is candidate material for detector.

The ferroelectric and strain behavior of the Ba(Ti12yCey)O3 solid solutions was studied. Three phase transition temperatures were shifted with increasing Ce concentration, and pinched at y 50.06. The samples could be structurally indexed by x-ray diffraction in a tetragonal symmetry at y<0.06; and in a pseudo-cubic symmetry at y.0.06. The strain levels in the range of 0.15–0.19% at ;60 kV/cm wi...
