摘要

金属卤化物类包晶石是 X 射线探测和成像领域最有前途的候选材料。然而，铅基包晶石的自吸收性和毒性严重限制了其广泛应用。在此背景下，锆基卤化物类包晶石因其优异的稳定性、低毒性、合适的带隙、无自吸收、宽发射光谱等特点而备受关注。本研究采用蒸发结晶法合成了(C8H20N)2ZrCl6单晶，其斯托克斯位移高达203 nm，PLQY高达80.77%，且在180天内具有良好的稳定性。然后，组装好的 (C8H20N)2ZrCl6@PDMS 薄膜显示出良好的柔韧性（弯曲和拉伸）和 5.8 lp/mm 的空间分辨率。因此，这项工作不仅为探索具有宽带发射的无铅金属卤化物包光体提供了一条途径，而且还展示了用于 X 射线闪烁成像的柔性锆基闪烁体。

Molecule design enabled high efficiency flexible zirconium-based lead-free perovskite scintillator

Metal halide perovskites are the most promising candidates in the field of X-ray detection and imaging. However, the self-absorption and toxicity of lead-based perovskites severely limit their widespread application. Herein, zirconium-based halide perovskites have attracted much attention due to their excellent stability, low toxicity, and suitable bandgap, self-free absorption, wide emission spectrum. In this work, (C8H20N)2ZrCl6 single crystals are synthesized by evaporation crystallization, which presents a large Stokes shift of 203 nm, a high PLQY of 80.77%, and good stability over 180 days. Then, the assembled (C8H20N)2ZrCl6@PDMS films show good flexibility (bending and stretching) and a spatial resolution of 5.8 lp/mm. Thus, this work not only provides a route to explore lead-free metal halide perovskites with broadband emission but also demonstrates flexible zirconium-based scintillators for X-ray scintillation imaging.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
