| 抄録: | Electroluminescence (EL) properties of organic light-emitting diodes (LEDs) under an external magnetic field were investigated for observation of spin-polarized luminescence. When an external magnetic field was applied to organic LEDs with an Fe cathode, circularly polarized light was observed, while devices with an Al cathode did not show such behavior. In order to confirm whether the circularly polarized light was certainly due to spin-injection or not, photoluminescence (PL) property of Alq_3 (tris-(8-hydroxyquinolinato)-aluminum) film on Fe and that of Alq_3 film on Al under an external magnetic field were investigated. In the case of Alq_3 on Fe film, degree of circular polarization from EL was much higher than that from PL. This suggested that circular polarization on EL was mainly due to spin-injection. c 2006 Elsevier B.V. All rights reserved. |
