Core–shell nanocrystals (C–S NCs) are an essential class of materials whose structural engineering has attracted wide attention due to their tunable optical and electrical properties, especially noble metal@semiconductor (NMS) C–S NCs with flexible plasmon-exciton coupling. Due diverse critical applications, aqueous biological herein we propose topological strategy enabled by cation exchange reactions (CER) synthesize various plasmonic Au@semiconductor NCs, in which environmentally friendly triphenylphosphine (TPP) is used as initiator instead inflammable tributyl phosphine (TBP). The introduction the milder, solid TPP facilitated a new CER for synthesizing tailored chalcogenide compositions morphologies. For example, as-synthesized Au@ZnS NRs had better absorption biocompatibility exhibited excellent photodynamic therapy efficacy.

Plasmonic metal/semiconductor hetero-nanostructures have attracted tremendous research interests in optoelectronic devices, photocatalysis and photothermal therapy, related fields. Among various mechanisms of localized surface plasmon resonance (LSPR) induced enhancements, the mechanism LSPR-induced hot carrier injection has emerged as a particularly powerful efficient process for modulating charge dynamics, especially photocatalysis. The efficiency these injections relies on robust metal–semiconductor interfaces, with performance heavily influenced by composition, crystallinity, atomic structure multi-interfaces involved. This letter explores injection, highlighting recent advances emphasis multi-interfacial engineering to optimize dynamics utilization. These interface-regulated processes, combined enhanced photocatalytic performance, provide new opportunities further advanced wide range photoelectric conversion applications.

Achieving precise control over the construction of efficient charge transport channels through self-assembly engineering represents a highly effective strategy for synthesis organic supramolecular photocatalysts. Herein, tetragonal zinc meso-5,10,15,20-tetra(4-pyridyl) porphyrin (ZnTPyP) nanorods (T-ZnTPyPs) and hexagonal ZnTPyP nanowires (H-ZnTPyPs) were synthesized by varying assembly temperature. H-ZnTPyPs demonstrated photocatalytic hydrogen production rate (183 mmol/g/h) that was 14.62 times greater than T-ZnTPyP (13 mmol/g/h). This significantly enhanced activity is primarily attributed to distinct well-defined molecular arrangements H-ZnTPyPs, which support continuous linear long-range electron transfer pathways π-π stacking. Conversely, heat manipulation used in T-ZnTPyPs limits participation water molecules crystalline stacking arrangements, leading lattice distortions disrupt interactions impede pathways. research presents novel modulating optimize

Constructing patterned film photoanodes with economizing raw chemicals but enhancing photoelectrochemical (PEC) performance is attractive for practical applications. However, simultaneously optimizing light scattering and interfacial charge transfer through plasmonic enhancement remains challenging. Herein, we developed a novel photoanode featuring Au grids nanometer-thick CdSe layer (Au grid-CdSe) well-organized heterointerfaces, fabricated via facile colloidal topochemical strategy. This design leverages the synergistic coupling between plasmons excitons in heteropatterned films. The underlying serve dual functions: as an electron collector reflector. Their highly ordered Bragg structure effectively scatters incident into ultrathin layer. Furthermore, CdCl2 surface passivation of Au(grid)-CdSe photoanode, based on this unique absorption/reflector architecture, yielded photocurrent density 4.51 mA cm-2, representing significant enhancement. Compared to similarly prepared Au-CdSe heterofilms, passivated films exhibited 2.0-fold higher PEC hydrogen evolution performance, maintained excellent stability over 26 h, reduced consumption by 32%. strategy offers pathway improving semiconductor-based optoelectronic devices.

Herein, study synthesizes atomic‐thin (≈1.6 nm) 2D copper sulfide (AT‐CuS) plasmonic nanocrystals find its extraordinary conversion efficiency (PCE) reaching up to 94.3% at second near‐infrared (NIR‐II) window. Photophysical mechanism studies reveal that strong localized surface plasmon resonance (LSPR) out‐of‐plane size effect of AT‐CuS induce optical absorption non‐equilibrium carrier scattering, resulting in a significant carrier‐phonon coupling (7.18 × 10 17 J K −1 s m −3 ), ultimately enhancing heat generation. Such nanomaterial demonstrates leastmes stronger NIR‐II photoacoustic (PA) signal intensity than most commonly used miniature gold nanorods, together greater biocompatibility photo‐/thermal‐stability, enabling noninvasive PA imaging brain microvascular living animals.
