摘要

Flexible scintillator screens with environmental stability, high sensitivity, andlow cost have emerged as candidates for X-ray imaging applications. Here, alarge-scale and cost-efficient solution synthesis of the vacancy-ordered doubleperovskite Cs_2ZrCl_6, which is characterized by thermal activation delayedfluorescence (TADF) dominated by triplet emission under X-ray irradiation,is demonstrated. The large Stokes shift and efficient luminescence collectionof TADF effectively ensure the light outcoupling efficiency. Further,flexible X-ray scintillator screens with an area of 400 cm~2 are prepared usingpoly(dimethylsiloxane) (PDMS) as the carrier, exhibiting excellent scintillationproperties with light yields as high as 49 400 photons MeV~(?1), spatial resolutionsup to 18 lp mm~(?1) and detection limits as low as 65 nGy s~(?1). Finally,the high-quality imaging results of non-planar and dynamic objects by suchscreens are demonstrated. It is believed that the explored Cs_2ZrCl_6@PDMSflexible scintillator screens would offer a big step toward expanding the applicationrange of scintillators in different environments.
