- Abstract
- As potential lighting-emitting devices, electrochemiluminescence (ECL) devices are promising in terms of device structure and fabrication and involve low processing cost compared to organic light-emitting devices (OLEDs). Herein, liquid electrolyte-based multi-colored ECL devices (ECLDs) were prepared with organic materials dissolved in electrolyte solution, which generated red, yellow, green, and blue emissions under an applied square-wave AC bias voltage. Among the four different emissive colors, yellow showed a strong and stable emission, which enabled quantitative measurements, including a luminance of 12 cd m-2 at 4.5 V.
