Radiation Response Characteristics of Pr3+-activated SrO–Al2O3–TeO2 Glasses
We fabricated Pr3+-activated glasses having a composition of 10SrO–5Al2O3–85TeO2 (PSAT) for potential use as radiation detectors, and their photoluminescence (PL) and X-ray-induced scintillation properties were then characterized. The PSAT glasses showed several emission peaks in their PL spectra ow...

| description | We fabricated Pr3+-activated glasses having a composition of 10SrO–5Al2O3–85TeO2 (PSAT) for potential use as radiation detectors, and their photoluminescence (PL) and X-ray-induced scintillation properties were then characterized. The PSAT glasses showed several emission peaks in their PL spectra owing to the 4f–4f transitions of Pr3+. Furthermore, they exhibited typical PL decay times (0.09–0.86 ms), where the decay originated from the 4f–4f transitions of Pr3+. In the scintillation spectra of the PSAT glasses, three peaks at approximately 480, 618, and 636 nm were observed. The scintillation decay times were 0.747–0.840 ms, corresponding to the 4f–4f transitions of Pr3+. Furthermore, the PSAT glasses showed afterglow levels of 352–521 ppm, and the lowest afterglow level (352 ppm) was comparable to that of Tl-activated CsI single crystal. |
