“…[ 46 ] And the value of E4 also transcends that of Eu 3+ ‐activated boroaluminate scintillating glasses (18.40%), [ 15 ] and Eu 3+ ‐activated tungsten gadolinium borate scintillating glasses (8.87%). [ 48 ] Gradually increasing the X‐ray power from 0.08 to 3.20 W, the XEL spectra of E4, T8, and BGO were shown in Figure 6b; meanwhile, the corresponding integrated XEL intensities as functions of X‐ray powers were exhibited in Figure 6c. All samples’ XEL intensities are positively related to the powers of X‐ray, and the integrated XEL intensities always follow the trend of BGO > T8 > E4.…”

Though widely applied in light-emitting diode (LED) lighting and X-ray detection, respectively, rare-earth ions doped phosphor and scintillating single crystals still face many challenges in practicalities, like aging of package material and difficulty to construct tiny array structure. Using phosphate glass as the host is quite beneficial for solving these problems while enabling distinguished luminescence. Therefore, Eu 3+ and Tb 3+ doped phosphate glasses which, respectively, show strong red/green emissions are researched. Superior thermal stabilities (78.69% and 89.35% emission intensities remain at 150 °C) and high internal quantum efficiencies (87.3% and 68.6%) are found to guarantee the excellent photoluminescence performances. The brilliant X-ray excited luminescence properties are demonstrated by general 19.49% and 34.74% integrated emission intensities of that of commercial Bi 4 Ge 3 O 12 single crystal scintillator with the change of X-ray power. Meanwhile, Tb 3+ doped scintillating fiber is drawn. Finally, excited by 380 nm LED, color manipulation and white light generation are achieved in LEDs with a structure of stacked emitting layers (mainly Eu 3+ and Tb 3+ doped phosphate glasses). Many of the as-constructed white LED's performance parameters are much better than the commercial white LED. These results show that Eu 3+ and Tb 3+ doped phosphate glasses possess promising potential in LED lighting and X-ray detections.

“…Consequently, the glass simulated in this study represents a best case scenario, and slightly lower density glasses presented by Tillman et al [21] may need to be considered. Alternatively, higher density glasses in the europium-doped tungsten gadolinium borate system have been reported, achieving densities as high as 6.173 g cm −3 with increased europium dopant [54].…”

The high cost and low image quality traditionally associated with proton computed tomography (pCT) have prevented it from seeing significant use in clinical settings. A cheap, compact, high-density scintillating glass detector capable of being attached to existing proton therapy gantries may help address these concerns. The design of the detector allows for use in conjunction with single-proton counting reconstruction algorithms, as well as beam-based algorithms that do not resolve individual protons within an accelerator bunch. This study presents quantitative reconstructed images of proton stopping power from Monte Carlo generated pCT scans using the radiation transport code MCNP6, demonstrating the feasibility of proton imaging using this detector design. Relative error and contrast have been examined and compared for images reconstructed using two reconstruction algorithms: a standard filtered backprojection algorithm to act as a benchmark, and a variant of a pCT algorithm which utilizes the concept of distancedriven binning.

“…[6][7][8] Many scintillators such as organic compounds and inorganic compounds have been fabricated for scintillator applications, but there is no scintillator that fulfills all requirements simultaneously; thus, an appropriate scintillator is used for each application. [9][10][11][12][13] Time-of-flight positron emission tomography (TOF-PET) has gained attention in medical field, and a fast scintillator that shows both a fast scintillation decay time and a high scintillation light yield is expected for high image resolution. Ce-doped inorganic materials such as Cedoped Lu 2 SiO 5 are employed due to their intense emissions of the 5d → 4f transition of Ce 3+ , but the scintillation decay time is generally several tens of nanoseconds.…”

We fabricated hybrid composites, where various organic–inorganic layered perovskite-type compounds (C6H5C2H4NH3)2PbBr4, (C6H5CH2NH3)2PbBr4, and (C4H9NH3)2PbBr4 were incorporated into a nanoporous glass, and their photoluminescence and scintillation properties were investigated for fast scintillator applications. A photoluminescence peak derived from free excitons was observed at around 410 nm for all the samples. Furthermore, a sharp scintillation peak originating from excitons was detected from the hybrid composites with (C6H5C2H4NH3)2PbBr4 or (C6H5CH2NH3)2PbBr4, and the hybrid composite with (C6H5C2H4NH3)2PbBr4 showed the highest scintillation intensity. In addition, afterglow levels of the fabricated hybrid composites were 430–620 ppm, and the values were higher than that of a (C6H5C2H4NH3)2PbBr4 single crystal.
