dc.description.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 similar to 0.3 mu s and high-specific detectivity of similar to 2.4x10(12) Jones. The synergistic effect of these two components ultimately leads to a self-powered flexible all-perovskite X-ray detector that delivers high sensitivity of 600-1,270 mu C/mGy(air)cm(3) under X-ray irradiation and fast radiation-to-current response time. | - |
