“…The peak positions of the glow curves are consistent with the previous reports. (38,39) In addition, there are TSL signals at around 50 ℃, which implies some glow peaks at temperatures below 50 ℃. In the past work, several TSL glow peaks were detected at room temperature or lower.…”

CsCl transparent ceramics were prepared by the spark plasma sintering (SPS) method, and their optical, scintillation, and dosimetric properties were investigated. To evaluate the potential of the transparent ceramics, a CsCl single crystal was prepared by the vertical Bridgman-Stockbarger method. Regarding the luminescence properties, the vacuum UV (VUV)-excited photoluminescence (PL) and scintillation spectral features of the transparent ceramics were similar to those of the single crystal. Concerning the thermally stimulated luminescence (TSL) properties, the minimum detection limit of the transparent ceramics was 0.01 mGy.

“…In previous works, more complicated features at a similar peak temperature were observed in Ni-doped and Eu-doped CsCl. (23,24) Therefore, the observed glow peak is possibly related to the CsCl host since these materials have only the CsCl host in common. TSL dose response functions of the samples are shown in the inset of Fig.…”

Ce:CsCl transparent ceramics doped with different concentrations of Ce (0.01, 0.1, and 1 mol.%) were synthesized by spark plasma sintering, and their optical, scintillation and dosimetric properties were investigated. Regarding the scintillation properties, X-ray-induced scintillation spectra of the samples consisted of three emission peaks at around 280, 380, and 400 nm, which were due to the Auger-free luminescence and 5d→4f ( 2 F 5/2 and 2 F 7/2 ) transitions of Ce 3+, respectively. In addition, the samples showed thermally stimulated luminescence (TSL) and optically stimulated luminescence (OSL) with emission peaks centering at around 400 and 480 nm, in which the origins were attributed to the 5d-4f transitions of Ce 3+ and the host, respectively. In particular, the TSL was sensitive to X-rays, and the TSL signals as low as 0.1 mGy were measurable, while a linear response was confirmed up to 100 mGy.

Optical absorption, photoluminescence, and thermoluminescence emission studies are made on CsCI:Tb3' crystals at room temperature. The presence of impurities is confirmed by the characteristic OA band at 360 nm. Photoluminescence of these crystals shows characteristic Tb3+ emissions due to transitions from the 5D3 and 5D4 levels to various levels of the 'F septet. The glow curve studies clearly show the participation of terbium ions in the thennoluminescence process. The new 415 K glow peak, not observed in pure CsCl, is ascribed to the terbium ion in the vicinity of F centers. All the TL glow peaks give the characteristic emissions of Th'+ in addition to the emission due to the recombination of the F electron with V-type centers.

Thermoluminescence of CsCl:Eu crystals irradiated with γ-rays

Abstract: The optical absorption and TL studies of γ‐irradiated CsCl:Eu crystals show the participation of the divalent europium ions in the TL process. The glow curves show new peaks in the higher temperature regions at 418 and 441 K, not observed in pure CsCl.
