Abstract

This study investigates the effects of incorporating gold nanoparticles (Au NPs) into a MEH-PPV polymer on its fluorescent properties. Analysis of the fluorescence spectrum of the polymer reveals a significant increase in fluorescence intensity upon the addition of Au NPs. Further investigation using Laser Induced Fluorescence (LIF) spectra demonstrates that the purified polymer emits light at 480 nm and 532nm, with additional peaks attributed to energy transfer mechanisms. This study shows cases the potential of gold nanoparticles to enhance the fluorescence of light-emitting polymers such as MEH-PPV, thereby having implications for applications like LED fabrication, sensor development, and bio imaging. The results highlight the capability of gold nanoparticles to augment fluorescence intensity and energy transfer, opening avenues for future research and improvement.
