This investigation explores the impact of synthesized cerium oxide nanoparticles (CeO 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 CeO NPs concentration on the organic fluorophore was conducted using the Benesi-Hildebrand equation, the findings indicated a substantial transfer of energy between CeO NPs and 5PPD.
本研究探讨了合成氧化铈纳米颗粒（CeO NPs）对化合物5-苯基-1-吡啶-3-基-戊-2,4-二烯-1-酮在各种溶剂中的溶剂化显色行为和荧光共振能量转移（FRET）的影响。已使用理论和实验方法估算了该化合物的偶极矩。此外，使用贝内西-希尔德布兰德方程对CeO NPs浓度对有机荧光团的影响进行了分析，结果表明CeO NPs与5PPD之间存在大量的能量转移。
