Forscher beobachten Nanopartikel beim Wachsen

Analyse erlaubt Maßschneidern von Materialien für schaltbare Fenster und Solarzellen

(PresseBox) (Hamburg, )
Mit DESYs Röntgenlichtquelle PETRA III haben dänische Forscher das Wachstum von Nanopartikeln live verfolgt. Die Untersuchung zeigt, wie sich Wolframoxid-Nanopartikel aus einer Lösung bilden. Diese Partikel werden beispielsweise für intelligente Fenster benutzt, die auf Knopfdruck undurchsichtig werden, und kommen auch in bestimmten Solarzellen zum Einsatz. Das Team um Hauptautor Dr. Dipankar Saha von der Universität Århus stellt seine Beobachtungen im Fachblatt "Angewandte Chemie - International Edition" vor.

Für ihre Untersuchung konstruierten die Wissenschaftler eine spezielle Reaktionskammer, die für Röntgenlicht durchsichtig ist. "Wir benutzen feine Kapillaren aus Saphir oder Quarzglas, die das Röntgenlicht mühelos durchdringt", schildert Forschungsgruppenleiter Prof. Bo Iversen.
