A novel 1D organic optic-electronic nanomaterial using PPV (p-type) as shell and Alq3 (n-type) as core

摘要

In this letter, we prepared ID core-shell structured nanomaterial using n-type Alq3 and p-type PPV by coaxial electrospinning, which are expected to be a kind of valuable organic optic-electronic nanomaterial with p-n heterojunctions. The core-shell structured nanofibers of both PPV/Alq3 and Alq3/PPV were tried to prepare. Alq3/PPV core-shell nanofibers with slippery surface and obvious interface were successfully fabricated. Through comparing PL intensity of Alq3/PPV nanofibers with that of PPV, the heterojunctions could be formed at the interface of n-type Alq3 and p-type PPV. The novel core-shell structured Alq3/PPV nanofibers are potential applications of fabricating microano optic-electric devices.
