Abstract

The organic light emitting devices were investigated. The devices were fabricate dbased on the heterostructure of the hole transporter ladder-type poly (p-phenylere) and electron transporter 8-hydroxyquinoline Aluminum doped by dye pyrromethene. The experimental results have shown that the microcavity effect can be achieved by adjusting organic layer thickness. The full width at half-maximum of the electroluminescence spectra is about 26nm. This value is in good agreement with the theoretical estimation. The results were also indicated that the stability of the microcavity devices was improved as compared with the non-microcavity devices.
