The modified perovskites show high water repellen.y that can.be used as an.un.erwater X-ray scin.illator. X-ray images of aquatic organ.sms or other objects with a high spatial resolution.of10 lp·mm^(-1) at a big view field(32 mm × 32 mm) were obtain.d by scin.illation.screen. This hydrophobic perovskite scin.illator based on.molecular design.is of great promise in.un.erwater X-ray n.n.estructive testin. techn.logy developmen..
