Thermally Activated Delayed Fluorescence Zirconium‐Based Perovskites for Large‐Area and Ultraflexible X‐ray Scintillator Screens (Adv. Mater. 43/2022)

X-ray Scintillators An ultraflexible and stable large-area X-ray scintillator screen is reported by Jiawen Xiao, Zhifeng Shi, and co-workers in article number 2204801, prepared by loading the vacancy-ordered double perovskite Cs2ZrCl6 into poly(dimethylsiloxane). This large-area flexible scintillator screen not only has high light yield and low detection limit, but also enables high-quality imaging of nonplanar and dynamic objects.
