Superior scintillation property of Tb3+-doped sodium silicate glass

All‐Inorganic Glass Scintillators: Scintillation Mechanism, Materials, and Applications

“…[ 36 ] It is worth noting that although the Tb 3+ doped sodium silicate glass prepared by Li et al was damaged under high dose X‐ray irradiation, it could be completely recovered after a simple heat treatment process, which showed that it has excellent recovery performance (Figure 6e). [ 93 ] Another feature worth mentioning for these materials is their high light output (about one and a half times that of BGO, shown in Figure 6f) as well as excellent thermal stability (Figure 6g). [ 93 ]…”

“…The number of defects inside the glass has been reduced, in conjunction with the improved chemical environment around the luminescent center, resulting in a significant increase in light yield. [ 33,87,92,93,95 ]…”

“…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. [33] As shown in Figure 5b,c, fluoride nanocrystals in oxide glass exhibit much stronger radioluminescence while maintaining high transparency (65% at 550 nm).…”

[33,87,92,93,95] 2) The formation of nanocrystals favors the scintillation performance of glass, but the requirement for glass transparency limits the volume fraction of nanocrystals inside the glass, hindering the further improvement of its performance. Recent advances have led to improvements in the glass matrix and the heat treatment schedule, ensuring uniform formation of smallsized grains to achieve excellent transparency without sacrificing scintillation performance.…”
