![]() However, high sensitivity is needed for X-ray detectors to reduce the radiation dose applied to human bodies for the applications of medical imaging and security checks. N2 - X-ray detection is of great significance for medical diagnostics, industrial non-destructive inspection, nuclear plants and scientific research. This journal is © The Royal Society of Chemistry. At Northwestern University work on hard radiation detector materials was supported by a grant from the Department of Homeland Security ARI program (grant number 2014-DN-077-ARI086-01). This work has been financially supported by National Natural Science Foundations of China (U163112262), National Key Research and Development Program of China (2016YFE0115200), the Natural Science Foundation of Shaanxi Province (2019JQ-459), and the Fundamental Research Funds for the Central Universities (3102018jcc0019TS0408). T1 - High-sensitivity X-ray detectors based on solution-grown caesium lead bromide single crystals Due to its facile synthesis, low cost, long-term stability, and high detection sensitivity, CsPbBr3 is expected to be an outstanding candidate for commercialized sensitive X-ray detectors.", ![]() The optimized detector exhibited high sensitivity of 1256 μC Gy-1 cm-2 for 80 kVp X-ray detection under a relatively low electric field of 20 V mm-1, which was 60 times higher than that of commercially used α-Se detectors. By designing the detector in an asymmetric electrode configuration, ion migration was effectively suppressed under a high voltage with a low dark current and an outstanding photoresponse. Here, we reported sensitive X-ray detectors made of solution-grown inorganic lead perovskite CsPbBr3 single crystals and the synthesis of high-quality inorganic lead perovskite CsPbBr3 single crystals using an improved low temperature solution method, which exhibited high transmittance, mobility and mobility-lifetime products. ![]() Due to its facile synthesis, low cost, long-term stability, and high detection sensitivity, CsPbBr 3 is expected to be an outstanding candidate for commercialized sensitive X-ray detectors.Ībstract = "X-ray detection is of great significance for medical diagnostics, industrial non-destructive inspection, nuclear plants and scientific research.
