Abstract

The microcavity light emitting devices were fabricated based on ladder-type poly (p-phenyline) (LPPP) and doped tris (8- hydroxyquinoline aluminum Alq₃) heterojunction structure. The light emitting layers we LPPP with hole transportation and Alq₃ as electron transporter. ITO and AL were the hole and electron injecting. Experimental results showed that the microcavity effect has been achieved simply by adjusting thickness of the organic light emitting layers between the ITO and AL electrodes. The stability of the microcavity devices with the heterojunction structure based on LPPP and doped- Alq₃ was greatly improved. This can be ascribed to that the ladder-type structure of LPPP exhibited a higher thermal and chemical stability, and the intermolecular hydrogen bonding between the depant molecules was eliminated, led to decreasing nonvadiative centers.
