In this paper, a series of 3-inch (1 inch=2.54 cm) diameter Cs₂LiYCl₆∶Ce (CLYC∶Ce) crystals with LiCl molar ratios of 55%~60% were grown by vertical Bridgman method. XRD patterns of opaque initial end of the crystals show that the Li-rich group distribution ratio can effectively inhibit the generation of the Cs₃YCl₆ phase. The optimal molar ratio of LiCl for high quality CLYC is 57%, where the volume ratio of CLYC phase to the total ingot is the largest, and isometric complete length up to 80 mm. Scintillation properties such as relative light output, energy resolution and figure of merit (FOM) of ϕ76 mm×76 mm CLYC∶Ce crystal obtained under the optimal proportioning condition were tested. The results show that 4.88% energy resolution is measured at 662 keV of ¹³⁷Cs γ rays. The figure of merit (FOM) of pulse shape discrimination (PSD) measured with a ²⁴¹Am-Be neutron source is 4.18. The study indicates that CLYC∶Ce crystal has excellent neutron-gamma discrimination performance.
