Abstract
Using the Localized Surface Plasmon Resonance (LSPR) of metal nanoparticles to manipulate light is an important area of ongoing research. Fluorescent molecules are commonly used for the detection of disease biomarkers and one strategy for increasing the detection sensitivity is Metal Enhanced Fluorescence (MEF), where metal nanoparticles at their LSPR wavelength are coupled to fluorescent molecules. In this paper the electromagnetic mechanism involved in MEF due to Au nano-cylinders immobilized on glass slides are described. Using the Finite Difference Time domain technique the modified quantum yield for commercially available fluorescent dyes are calculated for molecules close to the metal surface as well as the electric field enhancements at the excitation wavelengths. The results of the analysis show that the modified quantum yield depends upon both the original quantum yield of the fluorescent dye and the emission wavelength. If two dyes of similar quantum yield are considered there will be higher fluorescent enhancement for wavelengths that are higher than the absorption peak of the nanoparticle array.
