— Electron paramagnetic resonance (EPR) was used as a quantitative method to measure charge carriers that are present in OLED devices under various bias conditions. Charge‐transfer reactions that occur at the cathode interface through the interaction of charge‐injection layers and charge‐transport layers were investigated.
