Two-dimensional BA2PbBr4-based wafer for X-rays imaging application

Abstract

As one of the most promising candidates for X-rays imaging materials, perovskites have received extensive attention. However, poor stability and undesirable ion migration are still obstacles to its development. In recent years, the successfully developed two-dimensional (2D) perovskite materials have skillfully solved the above-mentioned problems, but the preparation of their pure phase single crystals remains a great challenge. Here, a 2D perovskite single crystal, BA2PbBr4, was used as a representative model, which was grown via a simple synthesis method of the solution temperature lowering (STL), exhibiting a short fluorescence lifetime (6.82 ns), intense X-rays radioluminescence, and high environmental and temperature stability. Moreover, it has been used in X-rays imaging, which shows good imaging results and stability. This study demonstrates that 2D perovskites have great potential in low-cost X-rays imaging systems.
