Abstract

This article focuses on the development and characterization of zero-dimensional zirconium-based halide perovskite (C8H20N)2ZrCl6 single crystals and their composite films with polydimethylsiloxane (PDMS) for flexible X-ray scintillation imaging. The synthesized crystals exhibit a large Stokes shift of 207 nm, a high photoluminescence quantum yield (PLQY) of 80.77%, and strong environmental stability over 180 days. The (C8H20N)2ZrCl6@PDMS films demonstrate excellent mechanical flexibility, thermal and UV stability, and achieve a spatial resolution of 5.8 line pairs per millimeter in X-ray imaging, outperforming some existing lead-free scintillators. This work highlights the potential of lead-free zirconium halide perovskites as stable, efficient, and flexible scintillators for advanced X-ray detection applications.
