Growth of metal halide perovskite nanowires for X-ray detection applications
Metal halide perovskites are most famous for their rapid development in solar cells, but they are also promising materials for X-ray scintillation detectors. We are synthesizing CsPbBr3 nanowire arrays using solution growth, by using anodized aluminum oxide nanopores as templates.
Our first paper in this project showed that the nanowires have an impressive stability to air exposure, with samples exposed to air for 4 months still exhibiting comparable photoluminescence and UV stability to fresh samples [Zhang 2021].
The second paper demonstrated high-resolution X-ray imaging using these structures, with excellent radiation stability [Zhang 2022].
Most recently, we demonstrated 3D X-ray microscopy using these structures [Dierks 2022].
