In Situ Intrinsic Self‐Healing of Low Toxic Cs₂ZnX₄ (X = Cl, Br) Metal Halide Nanoparticles (Small 2/2024)

Metal Halide Nanoparticles In article number 2305755, Ben Aizenshtein and Lioz Etgar demonstrate the self-healing ability of Cs2ZnX4 (X = Cl, Br) metal halide nanoparticles (NPs). When subjected to local heating by electron beam irradiation, the NPs form nanoshells (NSs) that subsequently heal back to their original state within minute, restoring their original phase and structure. They exhibit excellent stability under ambient conditions for up to a month, making them suitable for self-healing scintillators.
