Paper Abstract

The light-emitting properties based on ladder-type poly (P-Phenylene) (LPPP) with carbon nanotubes were investigated. The light-emitting devices with the heterostructure are consisted of the hole transporter LPPP and the electron transporter Alq3. Carbon nanotubes of 1 wt % were added in LPPP. The microcavity effect could be achieved by adjusting organic layers between Au and Al electrodes. It was also found that the light emission intensity was further increased and the emission peak was narrowed after doping carbon nanotubes as compared with that of samples without carbon nanotubes. This may be ascribed to increasing conductivity and mobility of organic lagers via doping carbon nanotubes.
