Surface plasmon resonance of two-segmented Au—Cu nanowires in polycarbonate template

Surface plasmon resonance of two-segmented Au—Cu nanowires in polycarbonate template

Two segmented gold—copper nanowires were grown inside the pores of polycarbonate track (PCT) etched membranes from two separate solutions by the electrodeposition method. Optical absorption spectra of two segmented Au—Cu nanowires in PCT template showed a surface plasmon resonance peak at about 900n...

Zusammenfassung:Two segmented gold—copper nanowires were grown inside the pores of polycarbonate track (PCT) etched membranes from two separate solutions by the electrodeposition method. Optical absorption spectra of two segmented Au—Cu nanowires in PCT template showed a surface plasmon resonance peak at about 900nm for incident angle θ=65° but for θ=0 there are no peaks in spectra. This work is possibly useful as labels in biological assays or as embedded identification tags.
