Abstract
In this thesis, first we reduce the thickness of metal elecctrode in organic light-emitting diodes. Then we evaporate absorbing/re-emission organic film on top of the metal eletrode to recycle a portion of surface plasmon polaritons (SPPs) in organic light-emitting diodes to induce surface plasmon polariton mediated energy transfer and re-emission.This mechanism can enhance out-coupling efficiency in organic light-emitting diodes and may be utilized for achieving double-emitting organic light-emitting diodes with single-sided surface plasmon polariton medeiated energy transfer and with color tuning capability.
Next, we analyze organic light-emitting diodes with strong microcavity effects and double-sided surface plasmon polariton mediated energy transfer systematically. The structure is glass/ organic film (absorption/re-emission)/ metallic anode/ organic film/ metallic cathode/ organic film (absorpton/re-emission). We change the thickness of metallic electrodes to investigate the effects of strong microcavity combined with surface plasmon polariton mediated energy transfer for out-coupling efficiency, colors and viewing-angle characteristics in organic light-emitting diodes. The experimental results match calculated results fairly well.
