Perovskite CsPbBr3 single crystal detector for high flux X-ray photon counting and synchrotron X-ray detection (Conference Presentation)

Photon-Counting Detector (PCD) capable of resolving the energies of single X-ray photons is critical in medical imaging (e.g., Computed Tomography). A high count rate and negligible polarization is essential for a PCD. Besides, there has been a critical need to develop high-Z sensor for synchrotron X-ray facility. The very high X-ray fluxes (e.g., 1e6 – 1e12 photons/s/mm2) involved in both applications makes it very challenging for detector operation. Here, we demonstrate that our perovskite CsPbBr3 single crystal detectors have good performance for these applications.
