Dual-energy X-ray imaging (DEXI) is a cutting-edge technology that provides more detailed material-specific information than the traditional single-energy strategy. Herein, we designed and fabricated top-filter-bottom (TFB) sandwich structure scintillator for high-resolution DEXI within single exposure. More specifically, low- high-energy photons were sequentially absorbed by top bottom scintillators efficiently converted into their corresponding emission colors. By discriminating between these different spectra of transparent TFB scintillator, can provide not only unique energy but also an exceptional resolution approximately 18 lp/mm on stacked images surpasses most reported single-layer organic- metal halide-based scintillators. The conceptual demonstrations decomposition reconstruction in realized several biological objects. This breakthrough research paves way development architectures specifically DEXI.
