Abstract
AbstractRecently, perovskites have shown great promise as a semiconductor material with the advantages of low‐temperature fabrication, controllable band gap, and high carrier lifetime. In the field of X‐ray detection, a number of workers have developed green and stable and efficient lead‐free halide chalcogenides in pursuit of stable performance and biological safety. This article has done the following three works: It introduces the basic principles of X‐ray detection briefly. The outstanding works that have been done are summarized in terms of sensitivity, signal‐to‐noise ratio, and detection limit, and their laws are summarized. The optoelectronic properties of lead‐free halide perovskites are summarized, the prospects of lead‐free perovskites in the field of X‐ray detection are foreseen.
