“…T he search for new inorganic scintillators with high light yield (LY) has been the subject of many researches. [1][2][3][4][5][6] Eu-doped inorganic phosphors have attracted much attention for decades, and they show notably LY with remarkable energy resolution. 3,7) Up to now, bright Eu-doped scintillators such as Eu:CaI 2 , 8) Eu:SrI 2 , 3) Eu:CsBa 2 I 5 9) and, Eu:KSr 2 I 5 10) have been reported, and they show an excellent LY and energy resolution around 2%-3%.…”

Photoluminescence and scintillation characteristics of Eu-doped Ba2SiO4 were investigated. A broad emission band due to Eu2+ is observed at 500 nm, and the photoluminescence and radioluminescence decay time constants are about 397 and 515 ns, respectively. From the pulse height distribution of 57Co γ-rays, the light yield of Eu:Ba2SiO4 is ∼48 000 ph MeV−1, which is comparable with those of developed oxide scintillators showing a high light yield. The results demonstrate that Eu-doped Ba2SiO4 is a high-performance scintillator for X- and γ-ray measurements and characterized by excellent scintillation output and afterglow.

“…The other decay time constant of 72 ns (47%) is longer that of the PL, which may be due to a complex energy transfer process from the host crystal lattice to the emission centers, in common with some intrinsic scintillators reported previously. (11,(37)(38)(39) The pulse height spectra of Cs 3 PrCl 6 and the BGO reference are shown in Fig. 6.…”

A sample of Cs 3 PrCl 6 crystal was grown under vacuum using the vertical Bridgman-Stockbarger method. The excitation spectrum, monitored at an emission wavelength of 310 nm, showed at least two excitation bands at around 233 and 257 nm. These excitation bands corresponded to the transitions from 4f 2 ground states ( 3 H J and 3 F J ) to 5d excited states of Pr 3+ split by the ligand-field interaction and the spin-orbit coupling. Upon UV excitation at 233 nm, the characteristic Pr 3+ 4f 1 5d 1 →4f 2 emission bands were observed at 285 and 312 nm. The scintillation spectrum shows two emission bands peaking at 285 and 312 nm, which is consistent with the photoluminescence, and can thus be assigned to the transitions between the 5d 1 excited state and 4f 2 ground states owing to the Pr 3+ . The fast scintillation decay time constants were estimated to be approximately 11.7 ns (53%) and 72 ns (47%). The scintillation light yield reached 5900 ph/MeV.

“…In hostemission-type scintillators, common materials are semiconductor scintillators (15)(16)(17)(18)(19)(20) and some others. (21)(22)(23)(24)(25)(26) In the latter, the functionalities of absorption and emission are assigned to the host and emission center, respectively. (27) The recent trend of R&D is on the former type, and preferable emission centers are Ce 3+ , (28)(29)(30)(31)(32)(33)(34) Pr 3+ , (35)(36)(37)(38) some rare-earth ions, (39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51) and other ions that have electron transitions associated with luminescence.…”

Non-doped and 0.1, 0.5, 1.0, and 2.0% Ce-doped (Gd 0.4 Lu 0.6 ) 8 Sr 2 (SiO 4 ) 6 O 2 crystals were prepared and their optical and scintillation properties were investigated. Their X-ray diffraction (XRD) patterns confirmed that the Ce-doped samples did not contain an impurity phase, whereas the non-doped one contained some impurity phases such as Gd 2 SiO 5 and Lu 2 SiO 5 . The emission due to 5d-4f transitions of Ce 3+ was observed at 380-650 nm in both the photoluminescence (PL) and scintillation spectra of the Ce-doped samples. The scintillation light yields (LYs) of the 0.5 and 1.0% Ce-doped samples under 241 Am α-ray irradiation were ~230 and ~620 ph/5.5 MeV-α, respectively.
