Enhancement of X‐ray excited optical luminescence in a 100 µm‐thick diamond plate by introduction of defect states via electron beam irradiation and subsequent high‐temperature annealing is demonstrated. The resulting X‐ray transmission‐mode scintillator features a linear response to incident photon flux in the range 7.6 × 10⁸ to 1.26 × 10¹² photons s⁻¹ mm⁻² for hard X‐rays (15.9 keV) using exposure times from 0.01 to 5 s. These characteristics enable a real‐time transmission‐mode imaging of X‐ray photon flux density without disruption of X‐ray instrument operation.

利用X射线激发钻石中的X射线激发光学发光对同步加速器辐射进行高动态范围透射模式检测。

通过电子束辐照引入缺陷态并随后进行高温退火，证明了在100 µm厚的金刚石板上X射线激发的光学发光的增强。由此产生的X射线透射模式闪烁体对入射光子通量具有线性响应，对于硬X射线（15.9 keV），入射时间从0.01开始，在7.6×10 ⁸至1.26×10 ¹² 光子s ^-1  mm ^-2范围内至5 s。这些特性可实现X射线光子通量密度的实时传输模式成像，而不会中断X射线仪器的操作。
