Czochralski growth and scintillation properties of Li6LuxY1−x(BO3)3:Ce3+ single crystals

We report on Czochralski growth of Ce3+-doped mixed crystals of Li6Lu(BO3)3 (LLBO) and Li6Y(BO3)3 (LYBO) i.e. Li6LuxY1−x(BO3)3 (x=0.0, 0.5, 1.0) (LLYBO). Problems faced during the growth process and the techniques to overcome them are discussed. Single phase of the grown crystals is confirmed by powder X-ray diffraction (XRD) analysis. The grown crystals are characterized for their scintillation properties such as energy resolution, light yield, fluorescent decay time and α/β ratio under γ-rays and α-particles excitation. The X-ray induced luminescence is measured for the grown crystals.
