Iron–Gold Barcode Nanowires

Abstract: Gestreifte Drähte: Multifunktionelle (magnetisch und optisch) Eisen‐Gold‐Barcode‐Nanodrähte wurden elektrochemisch mithilfe nanoporöser Template hergestellt. Die Strukturanalyse durch TEM‐Elementlinien‐Scan und ‐Kartieren (siehe Bilder) belegt eindeutig die gut getrennten, bambusartigen Nanostrukturen aus Fe‐ und Au‐Streifen.

“…An enhanced intensity of the plasmon with less aggregation can be obtained when suitable dispersing solvent was used. In Au NWs, there is a minor shift in the absorbance band toward longer wavelengths at 660 and 770 nm, which can be attributed to shape the NWs and coupling between the Au NWs aggregation [21]. …”

“…2(a) defines the area as framed in the bright field image for mapping, and Fig. 3(b), (c), (d) represent the TEM elemental mapping of Co, Pt and Au, respectively, manifesting the homogenous distribution of the three elements throughout the nanowire [14], [25], [28]. The irregular lateral shape of the nanowire may come from the deposition process and/or being aggravated from removing the AAO template.…”

“…As already mentioned, a combination of magnetic properties and optical responses represents materials with improved characteristics. Fe-Au barcoded nanowires were fabricated by Lee et al (2007) using AAO templates by pulse electrodeposition, thus forming alternate iron and gold segments. These barcoded nanowires possess magnetic properties with the easy axis aligned parallel to the nanowires' long axis as well as the optical response via the absorbance of light in the visible part of the spectrum dedicated to the Au segments of different lengths and shapes (Daniel and Astruc, 2004).…”
