A shift in the absorption bands of BFPBI was observed in different solvents. PL spectral study of BFPBI was conducted in various solvents; peak maxima shift to larger wavelengths when polarity is raised. BFPBI has the ability to function as a selective fluorescence sensor for the identification of the Fe³⁺ ion. Other tested ions, including Pb²⁺, Ni²⁺, Co²⁺, Cd²⁺, Zn²⁺, Mg²⁺and Ca²⁺ have not considerable influence on the fluorescence. Interestingly, fluorescence intensity was restored upon the addition of H₃PO₄, indicating a reversible fluorescence behavior. The fluorescence quenching is attributed to PET mechanism. The limit of detection for Fe³⁺ was determined to 5 × 10⁻⁵ M, confirming the high sensitivity. Other tested ions exhibited negligible interference, demonstrating high selectivity. A 1:1 stoichiometry was assumed, and the binding constant was calculated to 4.2 × 10³ M⁻¹ using the Benesi–Hildebrand model, indicating appreciable affinity for Fe³⁺. Investigation of the electric dipole moment and hyperpolarisability indicates that the imidazole derivative synthesized exhibits behavior of non-linear optics. This chromophore has a more suitable off-diagonal vs. diagonal tensorial component ratio that represents the anisotropy of in-plane non-linearity.</div></div>","PeriodicalId":20056,"journal":{"name":"Phosphorus, Sulfur, and Silicon and the Related Elements","volume":"201 3","pages":"Pages 318-327"},"PeriodicalIF":1.6,"publicationDate":"2026-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147571032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesis involves preparing ZnO nanoparticles <em>via</em> a precipitation method, followed by extracting and incorporating silica from rice husk through acid-base treatment. The resulting ZnO/SiO₂ nanocomposites were characterized using X-ray diffraction (XRD), Fourier-transform infrared (FTIR), Brunauer-Emmett-Teller (BET) analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and photoluminescence (PL) spectroscopy. XRD analysis confirmed the formation of the wurtzite hexagonal phase of ZnO and the amorphous nature of SiO₂. BET analysis revealed a significant increase in surface area for ZnO/SiO₂ (204 m²/g) compared to ZnO alone (33 m²/g), attributed to the mesoporous structure of the SiO₂ shell. SEM images showed reduced nanoparticle agglomeration after silica composing. PL spectroscopy demonstrated enhanced UV emission and a reduction in defect-related emissions in the ZnO/SiO₂ nanocomposite, indicating improved charge separation and reduced recombination. This green synthesis approach, which utilizes rice husk, offers an eco-friendly and cost-effective method for fabricating high-performance ZnO/SiO₂ nanocomposites, making them suitable for various photocatalytic applications.
