However, their practical application is severely hindered by inefficient triplet exciton utilization and severe self\u2010absorption caused by small Stokes shifts. Here, we present a flexible organic scintillator film (DMAc\u2010TRZ@PDMS) that simultaneously addresses these limitations through the integration of a thermally activated delayed fluorescence (TADF) emitter into a crosslinked polydimethylsiloxane (PDMS) matrix. The composite exploits a large Stokes shift to eliminate spectral overlap, effectively suppressing reabsorption losses during photon propagation. Meanwhile, efficient reverse intersystem crossing (RISC) enables effective triplet exciton harvesting. The resulting scintillator exhibits a linear x\u2010ray response with an ultralow detection limit of 69.19 nGy s\n \u22121<\/jats:sup>\n . Benefiting from the elastomeric PDMS network, the film achieves outstanding mechanical flexibility and stable emission under deformation. Notably, the scintillator delivers a high spatial resolution of 22.9 lp mm\n \u22121<\/jats:sup>\n for organic\u2010based systems, enabling high\u2010resolution, nondestructive x\u2010ray imaging of microstructured objects with exceptional contrast. This work establishes a rational strategy to overcome the fundamental limitations of organic scintillators by combining TADF photophysics with soft\u2010matter engineering.\n
