Hybrid lead-halide perovskites have recently emerged as a promising new class of high-Z semiconductors for direct X-ray detection, combining strong X-ray absorption, effective ambipolar charge transport with solution-processable single-crystal growth. Over the past few years, perovskite-based detectors have demonstrated rapid progress, achieving performance metrics that approach or rival...

I would also like to take this opportunity to propose a contribution for the workshop, based on a project we have been developing at the Brazilian Synchrotron Light Laboratory. Our work focuses on inorganic perovskites (CsPbBr₃) as high-Z sensor materials for hybrid detectors. We recently published our first results [1], covering material synthesis, characterization, and detection simulations....

Lead-free perovskite-inspired materials have emerged as promising candidates for direct X-ray detection. Herein, we report a scalable, single-step synthesis of Cs3Bi2I9 nanocrystals (NCs) with a high effective atomic number (Z value) directly from their precursor powders through an ultrasonication approach. By precisely controlling the precursor ratio and ligands, we achieve uniform and highly...
