Boosting Scintillation Yield in Cs3Cu2I5 Single Crystals via Europium (II) Incorporation toward High-Resolution and Fast X-Ray Imaging

Popis výsledku v původním jazyce

Low-dimensional halides (LDHs), in particular Cu(I)-based halides, are attracting great attention due to their non-toxic nature and efficient radioluminescence. Nonetheless, these LDHs still suffer serious scintillation yield loss due to nonradiative exciton-exciton/exciton-defect interactions, which poses a significant challenge for X-ray imaging applications. Herein, an exciton-harvesting strategy is proposed to enhance the scintillation yield of 0D Cs3Cu2I5 single crystals by Eu2+ doping. It is demonstrated that the 5d-4f transitions and charge transfer process of Eu2+in the Cs3Cu2I5 host can mitigate nonradiative energy dissipation effectively, possessing a high scintillation performance. Additionally, based on their X-ray excited radioluminescence properties, the Cs3Cu2I5:Eu2+ single crystals achieve high-resolution and fast X-ray imaging, resolving fine structures in a 300-mesh copper grid (≈50 µm) and clearly capturing dynamic profiles of a chopper blade operating at 180 Hz. This advancement establishes a novel design strategy for developing highly efficient scintillators toward high-resolution and fast X-ray imaging applications.
