Abstract :
We have grown mixed crystals of Li6Gd(BO3)3 and Li6Lu(BO3)3, Li6LuxGd1-x(BO3)3, doped with 3 mol% of Ce3+ ion by Czochralski technique (x = 0.0, 0.2, 0.5, 0.8, 1.0). In this paper we have discussed the growth problems during the crystal growth and technique to overcome. Powder X-ray diffraction (XRD) analysis have confirmed single phase of all the grown crystals. X-ray induced luminescence spectra are presented. Scintillation properties are presented as well such as; such as energy resolution, light yield and decay time under the excitation of γ-rays and α-particles.
