Balancing the Concentrations of Redox Species to Improve Electrochemiluminescence by Tailoring the Symmetry of the AC voltage |
| 초록 |
Electrochemiluminescence (ECL) corresponds to the light emitting phenomenon arising from excited luminophores generated by electrochemical reactions. Ruthenium(Ⅱ) (Ru(bpy)32+) complexes have been used as typical luminophores emitting red-orange-colored light. However, most studies have employed symmetric AC square waves to operate AC-driven ECL devices without considering the difference in stability between redox species. Therefore, we adjusted the duty-ratio (i.e. the fraction of positive pulse duration) and frequency of input AC square waves to balance the concentrations of reduced and oxidized ECL luminophores. As a result, we could greatly enhance the luminance of ECL devices. |
