Although Ag NPs are known for their excellent plasmonic properties, their susceptibility to oxidation in ambient conditions significantly reduces SERS activity. To overcome this, a femtosecond laser-assisted single-step novel approach is developed for synthesizing hybrid Ag-hBN nanocomposites via ablating Ag target in a solution of exfoliated hBN nanosheets, forming uniformly embedded Ag NPs on hBN nanosheets. The morphological characteristics and elemental compositions were validated by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and energy dispersive X-ray spectroscopy (EDS). TEM analysis revealed that Ag NPs averaged 15 nm in size, while hBN nanosheets had lateral dimensions of approximately 250 nm. The SERS activity of the prepared nanocomposites was investigated using dye and explosive molecules, achieving detection sensitivities of 1 μM and 100 μM, respectively, with high reproducibility. These detection sensitivities are significant as they demonstrate the potential of the Ag-hBN nanocomposites for sensitive and reliable detection of trace amounts of analytes. Notably, the Ag-hBN nanocomposites showed enhanced SERS activity compared to pure Ag NPs, with a 2.5-fold improvement for Nile blue, 3.6-fold for methylene blue, and 2.4-fold for RDX. The current study also demonstrates that hBN prevents Ag NPs’ oxidation and preserves the SERS functionality even at elevated temperatures. Furthermore, the NLO properties of the nanocomposites were investigated using the standard Z-scan technique, revealing two-photon and three-photon absorption coefficients of 3 × 10⁻⁴ cm/GW and 6.5 × 10⁻⁵ cm³/GW², respectively. The findings highlight the potential of Ag-hBN nanocomposites to enhance SERS and NLO devices, enabling future applications in sensing and photonics.</div></div>","PeriodicalId":19564,"journal":{"name":"Optical Materials","volume":"157 ","pages":"Article 116393"},"PeriodicalIF":3.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The composite was prepared via a co-precipitation method followed by calcination, which facilitated the uniform dispersion of TiO₂ quantum dots within the bentonite matrix. The resulting material exhibited a high specific surface area of 205.45 m²/g and an optimized band gap of 3.15 eV, making it suitable for visible light photocatalysis. The photocatalytic efficiency of Bent/TQ was evaluated under both xenon lamp irradiation and natural sunlight. The composite demonstrated a significant degradation rate constant of 23.35 × 10⁻³ s⁻¹, which is comparable to that of pure TiO₂ quantum dots (28.86 × 10⁻³ s⁻¹). Mechanistic studies revealed that the primary active species responsible for the degradation were hydroxyl radicals (•OH), generated through the interaction of photogenerated electron-hole pairs with H₂O molecules and molecular oxygen. Total Organic Carbon (TOC) and Chemical Oxygen Demand (COD) analyses were employed to assess the mineralization efficiency of the composite. The Bent/TQ catalyst achieved a COD removal efficiency of 84.5 % and a TOC reduction of 76.2 % after 240 min of irradiation under natural sunlight. Reusability tests indicated that the photocatalyst retained approximately 80 % of its original efficiency after seven consecutive cycles, though a slight decline was observed due to particle agglomeration under prolonged light exposure. The economic analysis suggested that the use of Bent/TQ nanocomposites could reduce operational costs by 29.12 % compared to conventional TiO₂-based systems, making it a cost-effective solution for large-scale wastewater treatment. This work highlights the potential of Bent/TQ nanocomposites as sustainable and efficient photocatalysts for environmental remediation, with future efforts aimed at enhancing their long-term stability and expanding their applicability to a broader range of pollutants.</div></div>","PeriodicalId":19564,"journal":{"name":"Optical Materials","volume":"157 ","pages":"Article 116408"},"PeriodicalIF":3.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore the effects of trace carbazole impurities, DCN with the same structure with L-DCN was preapared by choosing commercial carbazole. Moreover, RTP performance of L-DCN was further optimized by host-guest doping and tuning the mass ratios between polyvinyl alcohol (PVA) and L-DCN. Compared with crystals DCN, RTP performance of 1 % L-DCN@PVA was not significantly improved, but 1 % L-DCN/m-BCzCN constructed by dissolution and rapid volatilization showed almost equivalent afterglow lifetimes, with RTP lifetimes of 435.37 ms and quantum yield (Φ_P) of 0.06, achieving the expected goal.

The incomplete plasmonic hybridization model was proposed, which accurately describes the broadband spectral response. In contrast to full hybridization, incomplete hybrid modes can contain varying percentage admixtures of the primitive modes, allowing incident light in a broadband range to meet the momentum-matching condition. The analysis of the dependence of the reflection, absorption, and transmission spectra on the structural parameters further validates the results.
