Simple, Fast, Bright, and Stable Light Sources

In this work we show that solution‐processed light‐emitting electrochemical cells (LECs) based on only an ionic iridium complex and a small amount of ionic liquid exhibit exceptionally good performances when applying a pulsed current: sub‐second turn‐on times and almost constant high luminances (>...

Summary:In this work we show that solution‐processed light‐emitting electrochemical cells (LECs) based on only an ionic iridium complex and a small amount of ionic liquid exhibit exceptionally good performances when applying a pulsed current: sub‐second turn‐on times and almost constant high luminances (>600 cd m−2) and power efficiencies over the first 600 h. This demonstrates the potential of LECs for applications in solid‐state signage and lighting.
