However, one of the challenges impeding their clinical applications is the uncontrollable and unstable interfacial reactions between zinc implants and the corrosive media. In this study, we report a facile synthesis of metal–organic framework (MOF) nanocrystal coating with tunable thickness on the high-strength Zn-0.8Li alloy matrix for controlled corrosion. The as-obtained dense and uniform MOF nanocrystals form a strong connection with the zinc matrix via coordination bond so as to maintain the mechanical properties, and meantime provide highly rough surfaces exhibiting tunable wettability. The varied MOF coating thus regulate the interface structure between the zinc matrix and corrosive media to control the degradation behavior. Excellent antibacterial activity and biocompatibility are also achieved because of the unique topology morphologies, surface superhydrophilicity, as well as the dynamic Zn<sup>2+</sup> release.

However, the synthesis of high-quality quasi-2D perovskite thin films with controllable grain sizes remains a challenging task. In this study, we present a facile method for achieving quasi-2D perovskite thin films with controllable grain sizes ranging from 500 to 900 nm. This is accomplished by intermediate phase engineering during the film fabrication process. Our results demonstrate that quasi-2D perovskite films with smaller grain sizes exhibit more efficient bound exciton generation and a reduced stimulated emission threshold down to 15.89 µJ cm<sup>−2</sup>. Furthermore, femtosecond transient absorption measurements reveal that the decay time of bound excitons is shorter in quasi-2D perovskites with smaller grain sizes compared to that of those with larger grains at the same pump density, which is 230.5 ps. This observation suggests a more efficient exciton recombination process in the smaller grain size regime.
