“…Here, Ce-doped Lu 2 SiO 5 has an LY of 8700 photons/MeV. (64) For the 0.05% Ce-doped glass, the full energy peak was observed around 105 ch. In contrast, no full energy peak was clearly confirmed for the other glasses.…”

Ce-doped 20CsBr-20BaBr 2 -60ZnBr 2 glasses were synthesized by the conventional melt quenching method, and their photoluminescence (PL) and scintillation properties were investigated. In the PL and scintillation spectra, all the Ce-doped glasses showed broad emissions due to the 5d-4f transitions of Ce 3+ ions. Under 241 Am α-rays, the light yield of 0.05% Ce-doped glass was 40 photons/5.5 MeV-α.

“…The glow peaks at 200 °C and 380 °C are derived from F + and F centers in Mg 2 SiO 4 , respectively. 19,39,40) The TSL intensity at 200 °C increased with the increase of Dy concentration, and this trend corresponded to the rise in the PL intensity. On the other hand, this trend was possibly related to the charge compensation generating F + centers, which occurs when Dy 3+ ion was substituted with Mg 2+ ions.…”

In this study, we grew the Dy-doped Mg2SiO4 single crystals by the floating zone method to investigate the photoluminescence (PL) and thermally stimulated luminescence (TSL) properties. All the Dy-doped Mg2SiO4 showed the emission peaks at 480, 580, and 670 nm in PL and TSL spectra, and these peak wavelengths were typical for the 4f-4f transitions of Dy3+ ions. In the TSL glow curves, all the samples had glow peaks at 50, 200, 280, and 380°C. The TSL dose response function of the 1% Dy-doped Mg2SiO4 single crystals showed a good linearity across 1–10000 mGy.

“…The x = 0.01 sample had glow peaks at the same temperature as the x = 0 sample. Glow peaks at 190 and 380 ℃ have been reported (29,36,37) and are related to F + and F centers, respectively. (38,39) Figure 4(b) shows the TSL spectra of the x = 0 and 0.01 samples heated at 190 ℃.…”

“…This was due to the 5d-4f transitions of Ce 3+ ions. (29,30) No emission band due to Ce 3+ ions was observed under excitation at 250 nm. Therefore, no energy transfer from Tb to Ce occurred.…”

In this study, Mg 1.995−x SiO 4 :xCe, 0.005Tb (x = 0 and 0.01) single crystals were synthesized by the floating zone method and their photoluminescence (PL) and dosimetric properties were evaluated. In the PL process, emission peaks due to the 4f-4f transitions of Tb 3+ ions were observed in the x = 0 and 0.01 samples, and the emission peak due to the 5d-4f transitions of Ce 3+ ions was detected in the x = 0.01 sample. In the thermally stimulated luminescence (TSL) process, only emission peaks due to the 4f-4f transitions of Tb 3+ ions were observed in both samples, and the x = 0.01 sample had higher TSL intensity than the x = 0 sample. The x = 0.01 sample showed a lower detection limit of 0.01 mGy and a spatial resolution of 50.0 μm under X-ray irradiation.
