- Аннотация: The surface enhancement of noble metals nanodimers is analyzed to compare their perfor-mances on metal-enhanced fluorescence. We used the modified scheme of the Discrete Sources Method to investigate of the strong interaction between noble metal nanoparticles and the emitter. This new scheme enables to compute an excitation rate responsible for near field enhancement of several orders with high degree of accuracy. The excitation rate and quantum yield of the plasmonic structure are evaluated to obtain the required enhancement factor. Moreover, the effective enhancement factor of the plasmonic structure influence on the fluorescence of a nearby molecule was obtained by averaging all possible orientations the molecule. Optical theorem for the local source is employed to calculate Pursell factor and the quantum yield avoiding computation the nonradiative power. An optimal geometry of the nanodimmers needs to be determined for obtaining a maximum effective enhancement on the spontaneous emission of an emitter within the gap.
