Abstract
Ca, Ag, and Ge atoms quench the photoluminescence (PL) of an organic t hin film, tris-(8-hydroxyquinoline) aluminum (Alq(3)), a model organic material for organic light emitting diodes. The observed PL quenching behavior was similar for all three elements, independent of their met allic nature. Due to strong interactions at the Ca/Alq(3) interface, t he quenching was much less effective at submonolayer coverages. We hav e also observed that proper oxidation of Ca at the Ca/Alq(3) interface can significantly recover the quenched luminescence of Alq(3). (C) 19 97 American Institute of Physics.
