  text: Fast-emitting scintillators are essential for advanced diagnostic techniques,
    yet many suffer from low radiation attenuation. This trade-off is particularly
    pronounced in polymer scintillators, which, despite their fast emission, exhibit
    low density and low atomic numbers, limiting the radiation attenuation factor,
    resulting in low detection efficiency. Here, we overcome this limitation by creating
    a heterostructure scintillator of alternating nanometric layers, combining fast
    light-emitting polymer scintillator layers and transparent stopping layers with
    a high radiation attenuation factor. The nanolayer thicknesses are tuned to optimize
    the penetration depth of recoil electrons in active emissive layers, maximizing
    the conversion of X-rays to visible light. This design increases light output
    by up to 1.5 times and enhances imaging resolution by a factor of 2 compared to
    homogeneous polymer scintillators due to the ability to use thinner samples. These
    results demonstrate the potential of heterostructure scintillators as next-generation
    detector materials, overcoming the limitations of homogeneous scintillators.
