Abstract
The emission of light and the external coupling after appropriate excitons have been formed in the organic light-emitting devices have been investigated. A combined classical and quantum mechanical model was used to calculate the distribution of the internally emitted light into the externally emitted and various waveguided modes in an organic light-emitting device on planar substrates. The exciton lifetime in the OLED cavity was calculated by a Green's function formalism, with a focus on the non-radiative energy transfer to the cathode. Various efficiency measures as a function of the thickness of the indium-tin-oxide anode were calculated and the numerical results were in agreement with the measured external quantum efficiencies.
