The underwater X-ray imaging technology development is significant to subaqueous target recon-naissance/detection/identification,subfluvial archaeology,submerged resource exploration,etc.As the core of X-ray imaging detection,the scintillator has been plagued by inherent moisture absorption and decomposition,and strict requirements for seamless packaging and waterproofing.Here,we designed a manganese-doped two-dimensional(2D)perovskite scintillator modified by hydrophobic long-chain organic amine through the combination of component and doping engineering.The modified per-ovskites show high water repellency that can be used as an underwater X-ray scintillator.X-ray images of aquatic organisms or other objects with a high spatial resolution of 10 lp·mm-1 at a big view field(32 mm × 32 mm)were obtained by scintillation screen.This hydrophobic per-ovskite scintillator based on molecular design is of great promise in underwater X-ray nondestructive testing tech-nology development.
