Abstract

Thermally activated delayed fluorescence (TADF) X-ray scintillators have attracted increasing attention because of their theoretical ability to utilize 100% radiation-induced excitons. However, their scintillation performance is severely hampered by their typically low X-ray attenuation efficiencies or mechanochromic properties. Here, we demonstrate hybrid organic-inorganic TADF scintillators with remarkably high X-ray absorption cross sections based on non-mechanochromic Cu₂X₂ (X = Cl, Br, or I) nanoclusters. The Cu₂X₂ nanoclusters display radioluminescence light yields as high as 175 000 photons MeV^-1, attributable to their low self-absorption and spatially separated HOMO and LUMO orbitals. Furthermore, because of their non-mechanochromic properties, these nanoclusters can be formed into scintillating screens with excellent radiation and humidity stability via soft-pressing. The fabricated TADF scintillating screens display a high X-ray imaging efficiency, benefiting from their high light yields and high spatial resolutions (∼30 lp mm^-1). This work highlights the promise TADF Cu₂X₂ nanocluster-based scintillators have in meeting the demanding requirements of cutting-edge X-ray imaging.
