“…Huang et al prepared a series of Tb 3+ doped borosilicate aluminate glass scintillators with a high transparency over 80%. [ 65 ] Wantana et al measured and analyzed the physical and scintillation properties of Ce 3+ doped phosphate glass, and found that the density of the glass increased with the increase of Ce 3+ concentration. However, due to the concentration quenching, there was a maximum emission intensity at the concentration of 2 mol% Ce 3+ .…”

“…Previously, Tb 3+ and Ce 3+ were directly distributed in glass matrix. [37,65] To avoid luminescent quenching, forming nanocrystals with low phonon energy and fluoride microcrystals are mainly used at present, such as BaLuF 5 , Ba 2 LaF 7 , Lu 6 O 5 F 8 , CaF 2 , etc., [36,70,85,86] can disperse the rare earth ions and increase the luminescent quenching threshold.…”

“…Over the past decade, significant progress has been made in increasing the XEL light yield of glass scintillators. The XEL integrated intensity (%BGO) has increased gradually from its initial levels of 9.6% [37] and 26% [70] to a range of 40-70%, [65,85,86,97] and it has currently surpassed 140%. [33,87,92,93,95] In particular, the work of Teng et al has broken through the highest XEL integral intensity based on glass scintillator so far.…”

Glass scintillators have several benefits compared to the currently used single or polycrystalline scintillators, including non‐hygroscopicity, mechanical ruggedness, ease of producing customizable shapes, and low‐cost synthesis. The combination of the inert glass matrix and the embedded highly scintillating center render them significant materials for medical imaging and therapy, non‐destructive probing, nuclear monitoring, and high‐energy physics. Recently, great progress has been made in exploring new kinds of glass scintillator materials, improving imaging resolution for radiation detection, and developing an enormous range of commercial products. However, the majority of efforts have been devoted to the variation of materials, while rationally designing this new family of scintillators toward expected properties and applications is still lacking. In this review, the focus is specifically on advances in glass scintillators, including the scintillation fundamentals, material designing rule, and current application status, as well as future challenges and future directions.

“…The XEOL intensity of the Tb 3+ activators was enhanced after the incorporation of Gd 3+ ions, which was attributed to the increased electron population efficiency via energy transfer from Gd 3+ : 6 P 7/2 to Tb 3+ : 5 D 3 . 33,34 The Er 3+ : 4 G 9/2 and Ho 3+ : 5 G 5 levels are higher than that of Tb 3+ : 5 D 3 , and they can capture lots of secondary electrons in the conduction band (Fig. 3c).…”

Radiation detection is being revolutionized by integrating photonic elements into scintillators. In this study, a scalable and cost‐effective method is proposed to achieve tuneable emission enhancement across the visible spectrum by colloidal self‐assembly of photonic crystals on scintillator surfaces. This concept is demonstrated for Eu3+/Tb3+‐doped Gd and Ta oxides. Widely available and affordable colloidal nanospheres of SiO2 or polymethyl methacrylate are self‐assembled on these scintillators. The size of the nanospheres is carefully optimized to match the desired emission lines of Eu3+/Tb3+. The result is homogeneous and closely‐packed structures with clear photonic bandgap in the visible range. Under X‐ray excitation, the scintillators covered with the photonic layers exhibit enhanced light extraction in the direction perpendicular to the surface, compared to isotropic emission in the bare scintillator. Such scintillation directionality, when optically matched with a proper detector, will result in higher efficiency of the overall detection system. Moreover, X‐ray imaging demonstrates an enhancement of 25% in system resolution of the scintillator supplemented with the photonic layer compared to unmodified scintillators. The proposed method is scintillator‐ and nanosphere‐agnostic, thus offering a promising versatile approach for directing the scintillation light toward a photodetector and increasing detection system performance, including high‐resolution imaging applications.
