Abstract
The dynamics of the photo-excited states in crystalline thin films of a model oligo(para-phenylene vinylene) is studied with femtosecond pump–probe spectroscopy. The process of amplified spontaneous emission and the corresponding optical gain are shown to depend drastically on the crystallographic order present in the films. The results stress the important role of the molecular orientation in order to obtain efficient light-emitting conjugated organic devices.
