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 α/β ratio under the excitation of γ-rays and α-particles are also presented.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Single crystals of Li<SUB>6</SUB>Lu<SUB> <I>x</I> </SUB>Gd<SUB>1−<I>x</I> </SUB>(BO<SUB>3</SUB>)<SUB>3</SUB>: Ce<SUP>3+</SUP> are grown by Czochralski technique for the first time. </LI> <LI> Single phase of the crystals is been confirmed by X-ray diffraction analysis. </LI> <LI> Scintillation and luminescence properties are measured for the grown crystals. </LI> <LI> The grown crystals have got the potential to become a scintillation detector. </LI> </UL> </P>
