Self-powered flexible all-perovskite X-ray detectors with high sensitivity and fast response.

ABSTRACT: Perovskite materials have demonstrated superior performance in many aspects of optoelectronic applications including X-ray scintillation, photovoltaic, photodetection, and so on. In this work, we demonstrate a self-powered flexible all-perovskite X-ray detector with high sensitivity and fast response, which can be realized by integrating CsPbBr₃ perovskite nanocrystals (PNCs) as the X-ray scintillator with a CH₃NH₃PbI₃ perovskite photodetector. The PNCs scintillator exhibits ultra-fast light decay of 2.81 ns, while the perovskite photodetector gives a fast response time of ∼0.3 μs and high-specific detectivity of ∼2.4×10¹² Jones. The synergistic effect of these two components ultimately leads to a self-powered flexible all-perovskite X
