Summary: 2D lead halide perovskites with tunable bandgap and enhanced chemical stability are useful for designing optoelectronic devices. Reducing dimensionality can increase resistance to light-induced ion migration, but also decreases the efficiency of halide ion segregation and segregation rate constant, leading to a decrease in charge-carrier lifetime.

Summary: This study proposed a ligand engineering strategy to enhance the stability of Cs3Cu2I5 by inhibiting the oxidation of Cu+ to Cu2+. By using ethylenediaminetetraacetic acid (EDTA) as the organic molecule, the interaction between carboxyl groups and Cu+ was strengthened, resulting in improved light emission stability and properties of Cs3Cu2I5. EDTA-engineered Cs3Cu2I5 also showed enhanced photoluminescence quantum yield (PLQY) and was used in constructing a high-quality white-light emitting diode (WLED).

Summary: Researchers have discovered that lattice distortion in iodide/bromide mixed perovskites can suppress phase segregation, leading to increased ion-migration energy barrier. By using an approximately 2.0-electron-volt rubidium/caesium mixed-cation inorganic perovskite with large lattice distortion, they achieved an efficiency of 24.3% in all-perovskite triple-junction solar cells. This is the first reported certified efficiency for perovskite-based triple-junction solar cells.

Summary: Metal halide perovskite nanocrystals, fabricated with colloidal chemistry routes, have been shown to undergo interesting transformations when exposed to laser irradiation in liquids. In this study, transformations in large nanocrystals coexisting in different phases were induced using a femtosecond laser. The transformations included exfoliation, fragmentation, attachment, fusion, and anion exchange. The structure-photoluminescence relationships for the different samples were also analyzed.

Summary: Mixing bromine and iodine within lead halide perovskites can tune their optical properties, but it also leads to instability and degradation of device performances. This study shows that mixed-halide Ruddlesden-Popper perovskites preferentially occupy different sites, suggesting that they are not truly mixed.

Summary: We have developed a colloidal synthesis method for bismuth chalcohalide nanocrystals with a hexagonal phase. The structure of these nanocrystals can be described by the Bi13S18X2 (where X = Br and I) model. It was found that the presence of Bi24+ dimers, formed by columns of Bi atoms, and Peierls-type distortions are responsible for the anomalously low band gap and intervalence charge transfer in this material. Our findings and synthetic approach provide fundamental understanding for the use of hexagonal bismuth chalcohalides in diverse applications such as photocatalysis and thermoelectrics.

Summary: Researchers have used in situ synchrotron-based small-angle X-ray scattering and optical absorption spectroscopy to gain new insights into the nucleation, growth, and self-assembly of lead halide perovskite nanocrystals. They found that dispersed 3 nm Cs[PbBr3] agglomerates are the key intermediate species, which slowly nucleate into crystals and release Cs[PbBr3] monomers for further growth. They also discovered the mechanism of spontaneous superlattice formation when the nanocrystals reach a critical size of 11.6 nm.

Summary: Remarkable progress has been made in recent years in the development of low-dimensional perovskite-related materials. Various low-dimensional metal halide nanocrystals have been synthesized and investigated for compounds with low toxicity. These nanocrystals crystallize in various structures and dimensionalities, often exhibiting exciting optical properties. The improvement/manipulation of light emission from these nanocrystals and the possible origin of their light emission are discussed in this review, along with comparisons to their bulk counterparts and future research directions.

Summary: The interaction between BiBr3 and CsPbBr3 quantum dots is studied, and it is found that the addition of BiBr3 causes complete quenching of quantum dots' photoluminescence (PL), which can be fully recovered by the addition of excess PbBr2. Non-homogeneous surface trap formation is also observed. This study provides insights into the size-, ligand-, and metal-dependent quenching dynamics and reveals facet junctions as regions of enhanced surface reactivity.

Summary: In this paper, classical molecular dynamics (MD) simulations were employed to investigate the locations, binding modes and mobilities of carboxylate ligands on the different facets of CdSe nanocrystals. The results suggest that these features are influenced by the temperature of the system and the coordination number of the surface (Cd and Se) atoms. High ligand mobilities and structural rearrangements are observed with low coordination of Cd atoms, while undercoordinated Se atoms are found to form spontaneously on the nanosecond timescale, potentially playing a role in photoluminescence quenching.
