摘要

本研究探讨了一种柔性闪烁体的发光特性和灵敏度，该闪烁体由聚二甲基硅氧烷与掺杂了 1 mol% Pr2O3 荧光粉的 Lu2GdAl3Ga2O12 组成。这种柔性闪烁体是用模塑技术制造的。在室温下，研究了光子、质子和 X 射线激发下的发光特性。闪烁体显示出尖锐而狭窄的发射峰，这些发射峰归因于 f-f 转变，衰减时间为 14 μs。在 1.841 R 的 X 射线剂量下，它的灵敏度为 0.638 μC/R⋅cm3。这项研究展示了一种高性能柔性闪烁体，适用于医学成像和安全监控领域的先进辐射检测应用。

Scintillation properties of flexible scintillator composed on polydimethylsiloxane integrated with Lu2GdAl3Ga2O12:Pr2O3 phosphors

This study explored the luminescence properties and sensitivity of a flexible scintillator composed on polydimethylsiloxane integrated with Lu₂GdAl₃Ga₂O₁₂ doped with 1 mol% Pr₂O₃ phosphors. The flexible scintillator was fabricated using a molding technique. The luminescence properties were investigated under photo, proton, and X-ray excitation at room temperature. The scintillator exhibited sharp and narrow emission peaks attributed to f-f transitions, and a decay time of 14

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
