Wenn sich fluoreszierende Farbstoffmoleküle perfekt aneinanderschmiegen, entsteht etwas völlig Neues: Ein über viele Moleküle verteilter angeregter Zustand. Solche «kollektiven Anregungen» lassen sich vielfältig nutzen – etwa für organische Solarpanels, in Sensoren, für ultraschnelle Datenübertragung oder in der Mikroskopie. Empa-Forschern ist es gemeinsam mit Kollegen der ETH Zürich, der EPFL, des Paul Scherrer Instituts (PSI) und der IBM Research Zürich gelungen, solche chemischen Lichtverstärker zehnfach effizienter zu machen als bisher.
«Was wir hier sehen, ist eine Energieübertragung, die wesentlich schneller abläuft als in jedem Halbleiter», schwärmt Jakob Heier.
