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

TL;DR

This study investigates the surface plasmon resonance properties of two segmented gold-copper nanowires embedded in polycarbonate templates, revealing angle-dependent optical absorption peaks around 900 nm.

Contribution

It demonstrates the fabrication of segmented Au-Cu nanowires in polycarbonate templates and characterizes their angle-dependent surface plasmon resonance behavior.

Findings

Surface plasmon-polariton peak appears at ~900 nm at 65° incident angle.

No peaks observed at 0° incident angle.

Optical absorption spectra depend on incident angle.

Abstract

Two segmented gold copper nanowires were grown inside the pores of polycarbonate track (PCT) etched membranes from two separate solutions by electrodeposition method. Optical absorption spectra of two segmented Au Cu nanowires in PCT template were shown a surface plasmon- polariton peak appeared at about 900 nm for incident angle of theta = 65 degrees but for theta= 0 there are not any peaks in spectra.
