In article number 1901994, Wen Li, Wei Yan, Weiqing Yang, and co-workers unexpectedly find that 3D all-inorganic perovskites are exfoliated by water molecules and transformed into more intrinsic stable quasi-2D nanosheets in complete water conditions instead of leading to decomposition failure. This finding may not only provide a new path to investigating the intrinsic stability of all-inorganic perovskites, but also broadens the application of perovskites.
