Abstract

Surface Raman spectroscopy in ultrahigh vacuum is used to interrogate interfaces formed between tris(8- hydroxyquinoline) aluminum (Alq3) and vapor-deposited Ca. Vapor deposition of Ca onto Alq3 films results in the appearance of new vibrational modes consistent with the formation of a Ca-Alq3 adduct in which Ca is bound through the O of Alq3. In addition, the graphitic carbon is observed to form with the deposition of Ca onto Alq3 films. The frequency and relative peak height ratios of graphitic D-band and G-band observed are consistent with more disordered sp3-type carbon forming upon partial decomposition of the organic film.
