On Aug 23rd, Anti-perovskites with long carrier lifetime for ultralow dose and stable X-ray detection, a research paper authored by JXUST faculty, was published on line in Nature Photonics, which enjoys a high impact factor of 34.9.
The paper reported the development of a kind of materials with anti-perovskite structure. These materials enjoy advantages of long carrier lifetime (more than 2 ms), high sensitivity (1.0× 104 cGyair-1cm-2), low dark current (0.21 nA cm-2), low detection limit (2.4 ngyars-1) and a high stability.
After continuous irradiation with high-dose X-rays in air for 203 h, the photocurrent still has no obvious attenuation. It provides a new concept for the development of high performance photoelectric devices. This work is supported by the National Natural Science Foundation of China, the Natural Science Foundation of Jiangxi Province and the Key Laboratory Fund of Functional Crystalline Materials Chemistry of Jiangxi Province.
