Optical Properties of UHV-deposited thin Diindenoperylene Films — •M. Domhan, M. Heilig, and H. Port — Universitaet Stuttgart, 3. Physikalisches Institut, Pfaffenwaldring 57, 70550 Stuttgart

Thin films of Diindenoperylene (DIP) are deposited on weakly interacting substrates (Quartz, Si) at various substrate temperatures and studied by pico-second time-resolved fluorescence spectroscopy between 10K and 300K. The fluorescense spectra and decays are analyzed with respect to the nominal film thickness and the film morphology determined by AFM. Competing energy transfer and quenching processes are discussed.
