摘要

间接 X 射线探测器中闪烁膜的厚度会极大地影响其发光强度。然而,由于非相干光子的散射和衰减,厚闪烁膜往往会降低光产率。本文设计了一种高透明度的闪烁体玻璃陶瓷薄膜,在透明的非晶聚合物结构中原位生长 CsPbBr3 纳米晶体,以实现超稳定和高效的 X 射线成像。提出了晶体配位拓扑生长和原位成膜策略来控制晶体生长和薄膜厚度,既能防止光散射和 CsPbBr3 纳米晶体的不均匀分布,又能提供足够的薄膜厚度来吸收 X 射线,从而实现无团聚和无奥斯特瓦尔德熟化的高质量玻璃陶瓷闪烁体。这种厚度为 250 μm 的玻璃陶瓷闪烁膜实现了 326 nGyair s-1 的低检测限和 13.9 lp mm-1 的高空间分辨率。更重要的是,它在 X 射线辐照(辐射强度为 278 μGyair s-1 时仍能达到 95%,持续 3600 秒)、水浸泡(150 天)和高温储存(60 °C 下储存 150 天)条件下均表现出卓越的闪烁稳定性。因此,这项研究提出了一种用于 X 射线成像的超稳定柔性闪烁膜的构建方法,可减少光散射并提高分辨率。

Ultrastable and flexible glass−ceramic scintillation films with reduced light scattering for efficient X−ray imaging
The thickness of the scintillation films in indirect X−ray detectors can significantly influence their luminescence intensity. However, due to the scattering and attenuation of incoherent photons, thick scintillation films tend to reduce light yield. Herein, a highly transparent perovskite glass−ceramic scintillation film, in which the CsPbBr3 nanocrystals are in-situ grown inside a transparent amorphous polymer structure, is designed to achieve ultrastable and efficient X-ray imaging. The crystal coordination−topology growth and in−situ film formation strategy is proposed to control the crystal growth and film thickness, which can prevent light scattering and non−uniform distribution of CsPbBr3 nanocrystals while providing sufficient film thickness to absorb X−ray, thus enabling a high−quality glass−ceramic scintillator without agglomeration and Ostwald ripening. This glass−ceramic scintillation film with a thickness of 250 μm achieves a low detection limit of 326 nGyair s−1 and a high spatial resolution of 13.9 lp mm−1. More importantly, it displays remarkable scintillation stability under X−ray irradiation (radiation intensity can still reach 95% at 278 μGyair s−1 for 3600 s), water soaking (150 days), and high−temperature storage (150 days at 60 °C). Hence, this work presents a approach to construct ultrastable and flexible scintillation films for X−ray imaging with reduced light scattering and improved resolution.
