Intermolecular interaction and a concentration-quenching mechanism of phosphorescent Ir(III) complexes in a solid film.


Solid-state self-quenching processes of highly efficient Ir(III) phosphorescent emitters are investigated by the measurement of thin film photoluminescence quantum efficiency and transient lifetime as a function of doping concentration in a host matrix. The radiative decay rate constant is found to be independent from the average distance between dopant… (More)
