Abstract

We report on the intensity dependent exciton dynamics in optically excited tris (8-hydroxyquinoline) aluminum (Alq₃) films grown by organic molecular beam epitaxy that show a strong quenching of light emission at low temperature. We further report on the mode properties in plasmonic Alq₃ waveguides and on the exciton emission in InP nanowires which are coated with a thin Alq₃ films and Mg:Ag metal cluster layers.
