摘要：
Mixed crystals of Li6Gd(BO3)(3) and Li6Lu(BO3)(3), Li6LuxGd1-x(BO3)(3), doped with Ce3+ ion are grown by the Czochralski technique (x=0.0, 0.2, 05, 0.8, 1.0). The growth problems during the crystal growth process and the technique to overcome them are discussed in detail. Powder X-ray diffraction (XRD) analysis confirms single phase of all the grown samples. Laser induced luminescence spectra are presented. Scintillation properties such as energy resolution, light yield, decay time and alpha/beta ratio under the excitation of gamma-rays and alpha-particles are also presented.
