CsPbBr(3)-DMSO merged perovskite micro-bricks for efficient X-ray detection

Inorganic perovskite wafers with good stability and adjustable sizes are promising in X-ray detection but the high synthetic temperature is a hindrance. Herein, dimethyl sulfoxide (DMSO) is used to prepare the CsPbBr(3) micro-bricks powder at room temperature. The CsPbBr(3) powder has a cubic shape...

description Inorganic perovskite wafers with good stability and adjustable sizes are promising in X-ray detection but the high synthetic temperature is a hindrance. Herein, dimethyl sulfoxide (DMSO) is used to prepare the CsPbBr(3) micro-bricks powder at room temperature. The CsPbBr(3) powder has a cubic shape with few crystal defects, small charge trap density, and high crystallinity. A trace amount of DMSO attaches to the surface of the CsPbBr(3) micro-bricks via Pb-O bonding, forming the CsPbBr(3)-DMSO adduct. During hot isostatic processing, the released DMSO vapor merges the CsPbBr(3) micro-bricks, producing a compact and dense CsPbBr(3) wafer with minimized grain boundaries and excellent charge transport properties. The CsPbBr(3) wafer shows a large mobility-lifetime (μτ) product of 5.16 × 10(−)(4) cm(2)·V(−)(1), high sensitivity of 14,430 μC·Gy(air)(−1)·cm(−2), low detection limit of 564 nGy(air)·s(−1), as well as robust stability in X-ray detection. The results reveal a novel strategy with immense practical potential pertaining to high-contrast X-ray detection. [Image: see text] ELECTRONIC SUPPLEMENTARY MATERIAL: Supplementary material (further details of the characterization, SEM images, AFM images, KPFM images, schematic illustration, XRD patterns, XPS spectra, FTIR spectra, UPS spectra, and stability tests) is available in the online version of this article at 10.1007/s12274-023-5487-3.
