Abstract
Surface Raman spectroscopy in ultrahigh vacuum is used to interrogate interfaces formed between tris(8-hydroxyquinoline) aluminum (Alq(3)) and vapor-deposited Ca. Vapor deposition of Ca onto Alq(3) films results in the appearance of new vibrational modes consistent with the formation of a Ca-Alq(3) adduct in which Ca is bound through the O of Alq(3.) In addition, the graphitic carbon is observed to form with the deposition of Ca onto Alq(3) films. The frequency and relative peak height ratios of graphitic D-band and G-band observed are consistent with more disordered sp(3)-type carbon forming upon partial decomposition of the organic film.
