Luminescence and scintillation properties of Ce3+-doped SiO2–Al2O3–BaF2–Gd2O3 glasses

X-ray-Induced Scintillation via Energy Transfer of Gd3+ and Ce3+ in Silicate Glasses Composed of Heavy Elements

“…(38,39) In addition, the line at 275 nm is attributed to the 8 S 7/2 -6 I 7/2 transition. (40) Furthermore, the absorptions at 246 and 253 nm are attributed to the 8 S 7/2 -6 D 7/2 and 8 S 7/2 -6 D 9/2 transitions, respectively. (40,41) On the other hand, Ce-doped glass samples have a broad absorption in the whole UV region.…”

“…Among the glasses listed in Table II, Eu-doped SiO 2 glass, 146) Eu-doped CaF 2 embedded in 42SiO 2 -24Al 2 O 3 -9LiF-25CaF 2 -0.1Eu 2 O 3 glass ceramics, 158) Ce-doped 33.4SiO 2 -33.3LiF-33.1GdBr 3 glass, 177) Ce-doped 65SiO 2 − 20Al 2 O 3 -15BaF 2 -Gd 2 O 3 glass, 195) Ce-doped 30BaF 2 -20Al 2 O 3 -50B 2 O 3 glass, 199) Ce-doped Al(PO 3 ) 3 -CsPO 3 -0.5CsCl 206) glass, and Ce:BaO 2 -10Gd 2 O 3 -3SiO 2 glass 223) show a notable high light yield under γ-rays irradiation. In a typical manner, if the sample does not show a significant signal in the pulse height with γ-ray excitation, an α-ray is used as an irradiation source instead, since the energy of a typical α-ray source (5.5 MeV by 241 Am) is larger than that of typical γ-ray source (0.662 MeV by 137 Cs).…”
