摘要：

We report enhanced top emission from organic light-emitting devices by surface plasmon-mediated radiative energy transfer. A dye-doped dielectric acceptor layer was deposited onto the surface of a one-dimensionally corrugated silver cathode and was excited by the electroluminescence of a donor layer, which is located at the other side of the cathode. Ten times enhancement in emission intensity from the acceptor was observed compared to flat devices; this is due to the enhanced radiative energy transfer from the donor to the acceptor by the coupled surface plasmons on the opposite interfaces of the silver cathode.
