Paper Abstract

Based on the model of microcavity theory and transfer matrix theory, we measured the influence of complex cathode by introducing dielectric layer. Dielectric layer greatly influence the property of microcavity. Complex cathode may have obvious improvement to the trait of microcavity. Both in the instances considering microcavity effect and not considering, we compared the reflectivity, phase of reflection and light outcoupling efficiency of complex cathode with that of single layer metal cathode. To make the model simple, we do not consider complicated effect induced by interface absorbance and combination, we got the greatest improvement to outcoupling efficiency at certain instance. The efficiency of optimum structure is twelve times higher than that of single metal layer cathode. This confirms that dielectric layer can be used to improve the performance of organic metal cavity devices. Based on this kind of structure, unsymmetrical metal may reach great application.
