Abstract
A gadolinium-doped liquid scintillator with the mixed solvent as the matrix was prepared for a good comprehensive performance. In the ternary liquid scintillator, the β-diketonate was used as the complexing ligand of gadolinium (Gd), the combination of 20vol% pseudocumene (PC) and 80vol% linear-alkyl benzene (LAB) was chosen as the mixed solvent, and 2,5-diphenyloxazole (PPO) and 1,4-bis(2-Methylstyryl) benzene (bis-MSB) were the primary fluor and wavelength shifter, respectively. The characterizations based on the optimal formulation were conducted. The light yield was characterized by adopting the home-made optical platform device. The decay time was tested by adopting the time-correlated single photon counting (TCSPC) technique featured in high dynamic range of several orders of magnitude in light intensity. The experimental test results showed that the ternary liquid scintillator had a fairly good comprehensive performance.
