Light transfer from quantum-dot-doped polymer nanowires to silver nanowires

Light transfer between CdSe–ZnS core–shell quantum dot-doped polymer nanowires and silver (Ag) nanowires is achieved. Plasmons in the Ag nanowires can be effectively excited by photoluminescence emission from the quantum-dot-doped polymer nanowires under 532 nm laser excitation. Their efficient transfer makes it feasible to obtain waveguiding spectra at different propagation distances. Wavelength-converted waveguiding and wavelength-dependent dispersion effects occurred in polymer and Ag nanowires, respectively.
