X‐Ray Imaging
In article 2301002, Xutang Tao, Zeliang Gao, and co‐workers report a novel high‐temperature X‐ray detection crystal of SnTe3O8. SnTe3O8 X‐ray detector exhibits a stable high‐temperature sensitivity of 617 μC Gyair−1 cm−2 at 175 °C and a record low detection limit of 8.19 nGyair s−1 for 120 keV hard X‐ray. It shows potential applications in high‐temperature hard X‐ray detection.
Sensitivity and detection limit of X‐ray detectors are crucial for security checks, medical diagnoses, and industrial inspections. In this study, it is reported that introducing some cations containing lone‐pair electrons is beneficial for enhancing the Compton scattering effect and thus improving X‐ray detection performance. As an example, SnTe3O8 is selected and grown as a novel high‐temperature...
