Summary: Nonpyrophoric amines phosphines react with indium(III) halides in the presence of zinc chloride to synthesize colloidal indium phosphide (InP) quantum dots. However, the required P/In ratio of 4:1 makes it challenging to prepare large-sized and near-infrared absorbing/emitting InP QDs using this method. To overcome this, a synthetic approach using indium(I) halide as both the indium source and reducing agent for aminophosphine is introduced. This zinc-free method produces tetrahedral InP QDs with an edge length >10 nm and narrow size distribution.

Summary: All-inorganic perovskite nanocrystals (PNCs) show great potential for efficient and stable perovskite optoelectronic devices due to their suitable bandgap, broad absorption spectrum, and high color purity. However, the long-term stability of PNCs remains a major challenge. This study focuses on the instability factors of red-emissive PNCs and provides strategies to improve their stability and performance. The challenges in scaling up the production of PNCs are also discussed, along with possible future directions for the development of perovskite materials.

Summary: Indium phosphide (InP) Quantum dots (QDs) are a promising alternative to cadmium-based QDs due to their heavy metal-free and tunable luminescence. However, the photoluminescence performances of InP QDs, especially using the aminophosphine based synthesis method, still need improvement. In this work, a one-pot synthesis route of InP/ZnS red QDs based on tris(dimethylamino)phosphine (DMP) phosphorus precursor is presented. The addition of ZnF2 significantly improves the photoluminescence quantum yield (PL QY) of both InP and InP/ZnS QDs. The PL QY of InP/ZnS QDs is increased by 32.7% compared to those synthesized without ZnF2 treatment.

Summary: This study investigates the formation process of CDs without strong performance in water and aims to enhance their capabilities in bioimaging. The results show that a combination of acid properties and oxidation is crucial for the formation of red-emissive CDs, with key reactions involving oligomerization of o-PDA and crosslinking of oligomers to form aromatic structural segments. Conjugation with transferrin significantly improves the biocompatibility of CDs, which were successfully applied in bioimaging studies of neuroblastoma cell lines with gene amplification.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
