Scintillators convert high‐energy radiation into visible luminescence and have been widely applied in various significant fields such as nuclear fusion monitoring, high‐energy particle physics, medical imaging, and geological exploration. The scalable fabrication of scintillating fiber with the desirable combination of uniform size, superior radiation blocking ability, and excellent thermal/radiation stability is a major challenge. Here, a template solidification strategy for fabrication of full‐inorganic and efficient scintillating fiber is presented. The strategy involves the direct solidification of high‐density scintillator melt in a softened silica tube, allowing for the continuous production of small and uniform scintillating fiber. The fabricated scintillating fiber can effectively attenuate radiation up to ≈118 times higher than what conventional silica fiber can. In addition, it exhibits good compatibility with commercial fiber. Using this scintillating fiber, a radiation fiber detector is constructed and its application for online radiation monitoring is demonstrated.

用于实时辐射监测的全无机微纤维探头

闪烁体将高能辐射转换为可见光，并已广泛应用于核聚变监测，高能粒子物理学，医学成像和地质勘探等各个重要领域。具有均匀尺寸，优异的辐射阻挡能力和优异的热/辐射稳定性的理想组合的闪烁纤维的可扩展制造是主要挑战。在此，提出了一种用于制造全无机高效闪烁纤维的模板固化策略。该策略涉及在软化的硅胶管中直接固化高密度闪烁体熔体，从而连续生产小的且均匀的闪烁纤维。所制造的闪烁纤维可以有效地衰减辐射，其辐射强度是传统二氧化硅纤维所能达到的≈118倍。另外，它与商业纤维表现出良好的相容性。使用这种闪烁纤维，构建了辐射纤维探测器，并展示了其在在线辐射监测中的应用。
