Superfast long wavelength plastic scintillators

摘要

The acrylonitrile-styrene copolymer (AS) has been used as the matrix and B-PBD, TPB and DCM have been added as the solute for preparing fast red-emitting plastic scintillators. The fluorescence spectrum peak of the scintillators is at 610 nm, the fluorescence decay time is 2.57 ns. The methyl methacrylate with polarity monomer copolymer has been used as the matrix and B-PBD, LDS821 and LDS867 have been added as the solute for preparing super fast near infrared-emitting plastic scintillators. The fluorescence spectrum peak of the scintillators is at 800 nm and 820 nm, the fluorescence decay time is 2.20 ns and 0.95 ns respectively. (Atomindex citation 26:050694)
