We report on the optoelectronic properties of vacuum sublimed organic thin films of the oligothienyls ( Tn ) model systems. The Davydov splitting (DS) of the lowest exciton is about 0.3 eV and decreases with the conjugation length when going from T 4 to T 6. The lowest DS component is partially forbidden due to the crystal packing and the spectral activity occurs via Herzberg-Teller (HT) vibronic coupling. We show the real time dynamics of the HT coupling by coherent vibrational spectroscopy and the role of aggregates in the energy transfer processes within the films.

The Eu

Several sets of Eu-doped Y3Al5O12 (YAG) ceramic samples were synthesized by the vacuum sintering technique. Absorption bands at 250, 370 and 550 nm in samples were attributed to the charge transfer transition in the EuY2+ + F+ pair center.
