N2 - We have successfully fabricated well-defined Au-core and polydiacetylene-shell hybridized nanoparticles (NPs) having the suitable thickness of dielectric SiO2 layer between Au-core and polydiacetylene-shell by co-precipitation/microwave irradiation method, and subsequent solid-state polymerization process. The resulting hybridized NPs exhibited the significant enhancement of fluorescence intensity, increase in fluorescence quantum yield, and decrease in fluorescence lifetime, compared with polydiacetylene nanocrystals, due to the “emission enhancement” by localized surface plasmon resonance effect, and then would be one of the promising plasmonic nanomaterials toward optical device applications such as intense and stable point light sources.
