“…Red-emitting phyenyl polysiloxane-based scintillators have also been developed using PPO, BASF Lumogen Violet, and BASF Lumogen Red for the application in neutron detection. 44) The red emission is necessary to be coupled with Si avalanche photodiodes (APDs) in compact neutron detectors. Their scintillation light yields were up to 80% to that of EJ-212.…”

Recent development of organic scintillators is reviewed from the viewpoint of materials science. Design and crystal growth of organic crystalline scintillators, use of novel solvents and solutes in liquid scintillators, and development of plastic scintillators based on novel polymer hosts or novel fluorescent molecules are introduced. Additionally, development of loaded liquid or plastic scintillators is reviewed on the basis of two approaches of loading: molecules or nanoparticles. A disadvantage of organic scintillators has been their low scintillation light yields. Hence, materials design for improving scintillation light yields is introduced in detail with description on related excited state dynamics. Finally, future prospect for the improvement of scintillation light yield is briefly given.

“…Montbarbon et al reported a PVK-based plastic scintillator with a carbazole derivative (EHCz) and bis(2-methylstyryl)benzene (bis-MSB), showing a light yield of 7000 photons/MeV. The silicone-based plastic scintillators with 2,5 diphenyl-oxazole (PPO) showed a moderate light yield of 5600 to 8000 photons/MeV. − Unfortunately, to the best of our knowledge, few plastic scintillators have overcome the 10 000 photons/MeV limitation with polymer matrix other than polyvinyltoluene (PVT). , Several matrices have also been developed. Feng et al fabricated organic glass scintillators containing 10 to 99.8 wt % fluorenylsilanes with a light yield up to 16000 photons/MeV.…”

Plastic scintillators have been investigated for γ-ray detection with the promise of fast response, ease of scale up, and mechanical toughness. However, their low light yield has been a major limiting factor in the performance metrics. Herein, we report a cross-linkable fluorene derivative, 9,9-bis(4-vinylbenzyl)-9H-fluorene (SF), copolymerized with the plastic matrix, to facilitate effective Förster resonance energy transfer to boost the light yield. Noncurable 9,9-dimethyl-9H-fluorene (MF) and 9,9′-spirobifluorene (SBF) were also introduced to bridge the energy transfer gap between the polymer matrix and the primary dye. The plastic scintillator comprising 5 wt % SF and 20 wt % MF exhibits a light yield of 11 600 photons/MeV with a scintillation decay time constant of 2.3 ns.

“…However, recent alternatives have been proposed so as to afford different physical properties of the scintillators. Thus, poly(methyl methacrylate) and polysiloxanes are good candidates for the substitution of PS, even if PMMA is not a polymer which contains aromatic rings. Poly( N ‐vinylcarbazole) is of less industrial interest due to the difficulty to prepare large samples and its brittleness, the biggest reported sample displaying a volume of 48 cm 3 .…”

Attempting to prepare a plastic scintillator from a biobased polymer

A new plastic scintillator was prepared from a renewable polymer source. It is composed of the mighty 2,5‐diphenyloxazole and 1, 4‐bis(2‐methylstyryl)benzene molecules (PPO and bis‐MSB), acting as primary and secondary fluorophores, respectively, together dissolved in a polylactic acid matrix—PLA. This polymer is indeed considered as the biomass‐based equivalent of petroleum‐derived plastics in terms of mechanical and optical properties. Subsequent to the bis‐MSB emission, the emission wavelength is centered around 424 nm and the fluorescence decay time is in the nanosecond range. The material was fully characterized, and its scintillation performances were compared to a commercial PVT‐based plastic scintillator: EJ‐200. Like polystyrene‐ or polyvinyltoluene‐based scintillators, the material displayed a good response linearity with the energy of the incident gamma‐ray. However, the observed scintillation yield was rather modest, with a reported 500 ph/MeV value when excited with a gamma‐ray‐emitting 60Co source. This preliminary test could pave the way to new and renewable polymers for unexpected applications such as nuclear physics. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48724.
