| Outline of Final Research Achievements |
Light-emitting electrochemical cells (LEC) using ionic liquid are of interest for a new generation light source with high efficiency. We have observed the behavior of the ion distribution in LECs under operation using scanning transmission X-ray microscopy. We found that the operating current actually drives the ion movement, however, observed anion distribution was not fully described by a simple mechanism of self-organized p-n junction. Moreover, heterogeneic ion/polymer distribution due to the phase separation was found in the degraded cells.
