Abstract
The growth and scintillation properties of La0.97 (Cl0.05Br0.95)3:Ce0.03 crystals are reported. A 1-inch-diameter as-grown crystal is achieved by applying the vertical Bridgman technique, and one machined single crystal with sizes 18 mm × 8 mm × 8 mm is acquired. The scintillation properties of La0.97 (Cl0.05Br0.95)3:Ce0.03 crystals are presented. Under the excitation of UV (ultraviolet) light, the crystal exhibits two luminescent peaks centered at 358 nm and 382 nm. The light output is about 62000 ph/MeV while the energy resolution (ΔE/E) of this crystal at 662 keV is 4.55% of the full width at half-maximum. Additionally, the crystal photoluminescence decay time constant is 17.7 ns, which is significantly faster than that of LaBr3:Ce. The results indicate that the LaCl3 and the LaBr3 can form the anion solid solution crystal. The Lax (ClyBr1−y)3:Cei−x crystal is potentionally a promising scintillator.
