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.
