Plastic scintillator for pulse shape neutrons and gamma quanta discrimination

Effective Photo‐ and Triboluminescent Europium(III) Coordination Polymers with Rigid Triangular Spacer Ligands

“…The k nr for triboluminescence is four times larger than that for photoluminescence in [Eu 3 (hfa) 9 (tppb) 2 ] n crystals, These results indicate that mechanical crushing of molecular crystals leads to enhancement of the non‐radiative transition in the quantum process. We consider that the shockwave irradiation promotes effective mechanical crushing of organic crystals and the formation of the excited state of the ligands such as in the X‐ray scintillation effect …”

Plastic scintillators modifications for a selective radiation detection

“…In the same paper, the authors propose an unseen feature: spectral shape discrimination (SSD). On the same basis, the group of Adadurov reported twice the use of two different fluorophores in PS, one for collecting singlet states (1,4-dimethyl-9,10-diphenylanthracene, with addition of the wavelength shifter Luminophor 59: 1-phenyl-5-(4-methoxyphenyl)-3-(1,8naphthoenyl-1',2'-benzimidazole)-2-pyrazoline) and Eu(phen)(DBM)3 for collecting triplet states [30]. So herein the large decay time difference between the two dyes is exploited, as the singlet fluorophore displays a 13 ns decay time and the triplet fluorophore a 370 µs decay time.…”

Pulse-shape discrimination of the new plastic scintillators in neutron–gamma mixed field using fast digitizer card

“…Recently, a new class of plastic scintillating materials with PSD properties has been developed (Zaitseva, 2012;van Loef, 2014;Zhmurin et al, 2014;Blanc et al, 2014). In this paper, we study the PSD properties of the new plastic scintillator, EJ-299-33 (Zaitseva, 2012;Lawrence et al, 2013;Pozzi et al, 2013;Nyibule et al, 2014;Cester et al, 2014;Pozzi et al, 2014), and two liquid scintillators, BC-501A (NE-213) (Luo et al, 2013) and BC-519 (Horváth et al, 2000) using a two-parametric digital spectrometric system which we newly developed.…”
