英文摘要	The problems of the growth of Ce:Li6Lu(BO3)(3) (LLBO) crystal using Czochralski technique have been discussed. The supercooling, cleavage crack and inversion of solid-liquid interface were the main problems to grow high quality LLBO single crystals with fully transparent ingot. The thermal expansion coefficients of LLBO crystal were obtained from HTXRD data: alpha(a)=23.9 x 10(-6)/degrees C, alpha(b)=27.8 x 10(-6)/degrees C and alpha(c)=9.3 x 10(-6)/degrees C. The LLBO crystal with thickness of 1 mm grown from natural raw materials was sensitive to thermal neutrons and insensitive to high energy gamma rays (Cs-137). The decay time was statistically recorded to be about 38 ns by the digital oscilloscope. Therefore, LLBO crystal will be a promising fast scintillator for neutron detection. (C) 2014 Elsevier B.V.
