Abstract
We present a surface plasmon-mediated energy transfer based on an organic light-emitting device structure. In order to localize surface plasmons, silver nano clusters were deposited thermally close to the cathode with a 1-nm-thick LiF spacer. It was shown that the surface plasmon formed on the silver nano cluster provides a strong donor decay channel and increases the donor-acceptor dipolar interaction. Thus, photoluminescence results displayed 3.5-fold enhanced acceptor emission intensity, compared with those of sample which has no Ag nano cluster.
