Co‐assemblies of Silver Nanoclusters and Fullerenols With Enhanced Third‐Order Nonlinear Optical Response

Small Methods, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 10, 2025

Abstract Exploring potential third‐order nonlinear optical (NLO) materials attracts ever‐increasing attention. Given that the atomically precise and rich adjustable structural features of silver nanoclusters (Ag NCs), as well unique π‐electron conjugated system carbon‐based nanomaterials, a supramolecular co‐assembly amplification strategy to enhance luminescent intensity NLO performance hybrids two components, are constructed relationship between structures properties investigated. By combining water soluble Ag NCs [(NH 4 ) 6 [Ag (mna) ] (H 2 mna = 2‐mercaptonicotinic acid, abbreviated ─NCs hereafter) containing uncoordinated carboxyl groups with water‐soluble fullerene derivatives modified multiple hydroxyl (fullerenols, C 60 ─OH), delocalization is expanded owing non‐covalent hydrogen bonding effect Ag6─NCs ─OH, which provides feasible basis for realizing response. Then, co‐assemblies doped into PMMA matrix prepare composite film its evaluated by Z‐scan technique. Remarkably, effective absorption coefficients β orders magnitude higher than those assemblies at absence ─OH. This work showcases new approach amplifying responses greatly facilitates development integrated photonic devices.

This paper presents the research results on some characteristics of metal-organic framework material MIL-101(Cr) and its ability to remove nitrate from aqueous environments based photocatalytic reactions. was synthesized using hydrothermal method in laboratory. Techniques such as FE-SEM, XRD, FT-IR, BET were employed, demonstrating that porous structure is highly developed, with a specific surface area up 3017 m²/g characteristic octahedral crystal size ranging approximately 100 300 nm. Experimental show under UV light conditions at wavelength 365 nm power 250 W, MOF can catalyze removal light, achieving maximum efficiency 99% after 180 minutes reaction. The MIL-101 significantly improved, reaches nearly 100% within reaction time 40 when formic acid (HCOOH 46 mM) used hole scavenger.
