A research team from the Korea Advanced Institute of Science and Technology (KAIST) has discovered a way to make OLEDs more efficient. This new method can be used for flexible OLEDs, too.
The idea is to use surface plasmon. Silver nanoparticles were thermally deposited in a high vacuum on cathode. Since plasmons provide a strong oscillator decay channel, time-resolved photoluminescence (PL) results displayed a 75% increased emission rate, and continuous wave PL results showed a twofold enhanced intensity.
