摘要

本研究探讨了合成的氧化铈纳米颗粒（CeO2 NPs）对化合物5-苯基-1-吡啶-3-基-2,4-二烯-1- 1在不同溶剂中的溶剂致变色行为和荧光共振能量转移（FRET）的影响。用理论和实验方法估计了该化合物的偶极矩。此外，利用Benesi-Hildebrand方程分析了有机荧光团上CeO2 NPs的浓度，结果表明CeO2 NPs和5PPD之间存在大量的能量转移。

Spectroscopic and Computational Analysis of 5PPD-CeO₂: Insights from Fluorescence Quenching and FRET Studies.

This investigation explores the impact of synthesized cerium oxide nanoparticles (CeO₂ NPs) on the solvatochromic behaviour and fluorescence resonance energy transfer (FRET) of the compound 5-phenyl-1-pyridine-3-yl-penta-2,4-dien-1-one in various solvents. The dipole moments of this compound have been estimated using theoretical and experimental methods. Furthermore, the analysis of CeO₂ NPs concentration on the organic fluorophore was conducted using the Benesi-Hildebrand equation, the findings indicated a substantial transfer of energy between CeO₂ NPs and 5PPD.

期刊介绍： Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
