Abstract
- We have studied the increase of the radiative decay rate of heptamethine cyanine NIR laser dye within core-shell Ag/SiO<subscript>2</subscript> nanowires. The photoluminescence intensity and lifetime of the heptamethine cyanine dye are affected by the Ag nanowires. Both the photoluminescence intensity and the decay rate of the heptamethine cyanine dye are greatly enhanced by the Ag nanostructures and are caused by the interactions between the excited-state fluorophore and the local electric field near the metal particles.
