Abstract

The influence of the surface plasmon of gold nanoparticles on the optical
properties of the fluorescent nanoparticles in aqueous solution have been
investigated. The fluorescence of nanoparticles can be enhanced or quenched
in the presence of gold nanoparticles depending on the domination of energy
transfer mechanisms: radiating surface plasmon coupling emission or
F\"{o}rster energy transfer from fluorescent particles to gold particles,
which exciting absorbing plasmon. The fluorescence enhancement or quenching
is attributed to the increase or decrease of radiative recombination rates,
respectively. The parameters of the energy transfer between fluorescent
nanoparticles (dye molecules encapsulated in silica nanoparticles) and nano
golds have been estimated. The results show that the interactions between
nanoparticles depend on the size of both fluorophores (as donors) and gold
nanoparticles (as acceptors).
