Abstract

original image

Ausgehöhlt: In einer eleganten Methode wandeln Lochfraß- und Ätztechniken einkristalline Pd-Nanowürfel in Nanokästchen (siehe SEM-Bild) und Nanokäfige um, ohne dass exotische Template erforderlich sind. Durch das Leeren der Innenräume der Pd-Nanostrukturen lassen sich Oberflächenplasmonenresonanz-Signale zwischen 410 und 520 nm einstellen.
