“…[3][4][5][6] Because of their optical properties and high-frequency conductivity, metal NPs are widely used in optoelectronics and nanotechnology and to create microcircuits and nanosensors in order to accelerate the transport of individual pulses and signals by means of plasmon energy. [7][8][9] The methods of obtaining silver NPs are as follows: by pulse discharge in a liquid, 10 by laser ablation, 11,12 and by chemical reduction from aqueous solutions-see, for example, Refs. [13][14][15].…”

Plasmon amplification and quenching of the fluorescence and phosphorescence of anionic and cationic dyes in various media

et al. 2014

This paper discusses how the nanoparticles of a silver citrate hydrosol affect the fluorescence and phosphorescence intensity and lifetime of anionic and cationic dye molecules. It is found that, depending on the nanoparticle concentration of the silver hydrosol, there is both amplification and quenching of the fluorescence and phosphorescence of the molecules. Interaction mechanisms are observed between excitation by the molecules and by the silver nanoparticles.
