This work investigates the influence of silver nanoparticles (AgNPs) concentration on the plasmon-enhanced fluorescence (PEF) of pyrene molecules in solutions and embedded in nanocomposite polymer-based thin films. By employing numerical electromagnetic modeling to estimate AgNPs size and nanoparticle-fluorophore distance influence on PEF efficiency, and systematically varying the AgNPs concentration in experimental studies, we examine how their localized surface plasmon resonance modulates the fluorescence intensity and spectral characteristics of pyrene in aqueous solutions and AgNPs/pyrene/polyvinylpyrrolidone thin films fabricated via spin-coating. Our results demonstrate a non-linear relationship between AgNPs concentration and fluorescence intensity of pyrene, with an optimal pyrene-AgNPs volume ratios of 1:2 and 1:1 that maximize fluorescence enhancement factor for solution (~ 1.8 times) and nanocomposite thin film (~ 2.1 times), respectively. The role of polymer matrix for maximizing the PEF effect and preventing fluorescence quenching is discussed. These findings provide insights into the tunability of PEF in hybrid nanostructures and highlight the importance of nanoparticle concentration factor in designing efficient plasmonic fluorescence systems for sensing and photonic applications. |
