Abstract

In this work, we experimentally and theoretically investigate half-wavelength-thick Organic Light Emitting Diode (OLED) in a vertical microcavity. The latter is based on a quarter-wavelength multilayer mirror on one side and a thin aluminum semi-transparent layer on the other side. Two key parameters are studied for an optimal design of a cavity- OLED: the organic layer and the metallic cathode thicknesses. The experimental study shows that a 627 nm peak emission is obtained for a 127 nm-thick OLED hetero-structure. To achieve both desired optical transmission and effective electron injection, we investigate the influence of the Al cathode thickness on the performance of the microcavity devices. The experimental results are compared to those obtained by simulations of the emission spectra using the transfer matrix method and taking into account the organic emitter position inside the cavity.
