Light-emitting Electrochemical Cell (LEC) is expected as a new light emitting device. Among them, LECs using a phosphorus-based ionic liquids have made great progress by solving the conventional issues such as compatibility. We have been studying the operating mechanism of LEC comprised of SY-PPV and phosphorus-based ionic liquids by combining bias application and spectroscopy. This time, we will report mainly on the characteristics of the observed signal.
