In this section, we discuss two mechanisms that have been suggested to explain the resonant-coupling enhancing effect, namely, increase of IQE via emitter/plasmon coupling and increase of light extraction efficiency [LEE] by means of out-coupling of the generated photons.
Then, we took the average value on the extraction efficiency.
The main factors affecting the extraction efficiency have been optimised by means of a central composite design.
The first 10 samples were extracted three times to determine the extraction efficiency.
