	1	X-ray imager of 26-μm resolution achieved by perovskite assembly显示文摘Spatial resolution is an important criterion to evaluate the performance of a scintillation screen for X-ray imaging.Perovskite-based X-ray screen,usually made of powders or polycrystalline films,suffers from low spatial resolution(~200μm)due to the large thickness of scintillation layer despite of their compelling sensitivity to X-ray dose.In this work,a concentrated colloid of CsPbBr_(3)nanosheets was synthesized via a co-precipitation method at ambient condition.By drop casting,smooth scintillation screens of varied thickness were formed through self-assembly,which exhibited both high internal and external photoluminescence quantum yield(PL QY)(84.5%and 75.1%,respectively).The screen-based X-ray detector showed a high sensitivity down to 27 nGy/s,two orders of magnitude lower than the regular dose for medical diagnostics.Importantly,the screen of optimal thickness of 15μm showcased an unprecedented spatial resolution(26μm)when used for X-ray radiography,representing one order of magnitude improvement in perovskite community.
