Abstract
In this paper, three polymeric bases (styrene, vinyl toluene, methyl methacrylate (MMA)) plastic scintillators were synthesized by thermal and UV irradiation polymerization. The influences of the concentrations of the primary fluorescent agent 2.5-diphenyloxazole (PPO) and wave-shift agent 1,4-bis-2(5-phenyloxazoyl)benzene (POPOP) on plastic scintillators characterization were investigated. The results suggest that the maximum emission wavelength of synthesized plastic scintillators with different polymeric base are all around 423 nm matching with maximum response wavelength of general photoelectric devices, and its decay time with several nanoseconds has reached the same level as the EJ-200. The maximum light yield of the plastic scintillator was achieved when the mass ratio of PPO/POPOP is 1.0%/0.02% for the styrene plastic scintillators.
