Photoluminescence and scintillation properties of Eu3+-doped BaCl2–BaO–TeO2 glasses
Abstract Eu 2 O 3 -doped oxychloride tellurite glasses were fabricated, and their luminescent characteristics were investigated for glass scintillators. Luminescent peaks originating from the transition between 4f energy levels of Eu 3+ were observed at 577, 592, 612, 652, and 701 nm under 530 nm light. These luminescent peaks were also observed when irradiated with X-ray, and the maximum intensity was observed at a Eu 2 O 3 concentration of 3.0%. Furthermore, scintillation decay times of about 0.64 ms were detected from the Eu 2 O 3 -doped oxychloride tellurite glasses. Moreover, the 3.0% Eu 2 O 3 -doped oxychloride tellurite glass exhibited the lowest afterglow level (177 ppm) that was lower than that of a Tl-doped CsI single crystal.
