Here the researchers report on a WO3/Al/Al:Ag anode which is demonstrated in a red OLED with superior performance compared to the ITO reference device. Better performance is due to narrower emission spectrum, improved outcoupling, lower turn-on voltage/better charge injection.

Setfos was used to simulate the forward emission spectrum and performed mode analysis for different ETL thicknesses.

Paios was also used to perform Impedance Spectroscopy at different voltages to check injection/accumulation of charges, performed C-V to analyse onset and show Transient Electroluminescence.
