Summary: The addition of ethylammonium bromide (EABr) to the methylammonium tin iodide (MASnI(3)) perovskite precursor solution can regulate the crystallization dynamics, improve film morphology, and enhance efficiency and stability of the perovskite solar cells. The combination of EA(+) and Br- ions in the precursor solution results in a champion power conversion efficiency (PCE) of 9.59% and maintains 93% of initial efficiency after 30 days without encapsulation. This work provides a new strategy for high-efficiency tin-based perovskite solar cells.

Summary: Metal halide perovskites, as attractive photoactive materials, have shown outstanding performance in various optoelectronic applications. Among them, mixed-halide perovskites with finely tunable band gaps are particularly desirable for targeted applications. However, the photoinduced halide segregation often reduces the photoelectric stability of the materials. In this study, a post-treatment strategy of generating a two-dimensional passivating layer on the perovskite surface was adopted to selectively modulate trap-assisted recombination pathways. The results showed that this approach can improve the photocurrent response and mechanical properties of the perovskite, offering valuable guidance for developing next-generation optoelectronic applications.

Summary: We report a high photoluminescence quantum yield of 25% in colloidal two-dimensional tin iodide nanosheets that are synthesized by a hot-injection method, induced by structural reconstruction. The red-colored nanosheets transform to white hexagonal nanosheets upon washing or exposure to light, leading to an increase in bandgap and a large Stokes shift. The long photoluminescence lifetime is attributed to the formation of tin iodide clusters during the structural reconstruction. The stereoactive 5s(2) lone pair of tin(II) ions perturbs the excited state geometry of the nanosheets, facilitating the formation of self-trapped excitons. These broadband and intensely emitting metal halide nanosheets show promise for white light-emitting diodes.

Summary: Scintillator-based X-ray imaging has been developed using lanthanide(III)-Cu4I4 heterometallic organic frameworks (Ln-Cu4I4 MOFs) which consist of X-ray absorption centers ([Cu4I4] clusters) and luminescent chromophores (Ln(III) ions). The [Cu4I4] clusters absorb X-ray energy to generate triplet excitons through halide-to-ligand charge transfer (XLCT) and metal-to-ligand charge transfer (MLCT) state. These excitons excite Tb3+ to produce intense X-ray-excited luminescence through energy transfer. Tb-Cu4I4 MOFs exhibit high resistance to humidity and radiation, linear response to X-ray dose rate, and high X-ray relative light yield. X-ray imaging with Tb-Cu4I4 MOFs-based flexible scintillator film shows high spatial resolution.
