Dye molecules the key to faster energy transfer

EQ71 Farben 870When fluorescent dye molecules nestle perfectly together, something completely new is created – an excited state distributed over many molecules. Such collective excitations of fluorescent dye molecules have potential applications in, for example, organic solar panels, sensors, ultrafast data transmission and microscopy.

Researchers at Empa, ETH Zürich, EPFL, the Paul Scherrer Institute and IBM Research in Zürich, Switzerland, have now succeeded in making such chemical light amplifiers ten times more efficient than before.
