Abstract

<p>Electrochemiluminescence (ECL), a light-emitting phenomenon induced by electrochemical redox reactions, has potential applications in lightweight and flexible light-emitting devices. Previously, an ultrafast ECL response of <100 μs was successfully achieved under application of alternating current voltage by using a DNA-modified electrode including Ru(bpy)32+, an orange ECL material. In this study, we investigated effect of electrolyte composition on the fast responsive ECL in the DNA/Ru(bpy)32+ hybrid film-based ECL device. As a result, the ECL intensity and lifetime of ECL were improved by introducing additional Ru(bpy)32+ into the electrolyte solution. The increase concentration of Ru(bpy)32+ inhibited dissolution of aggregated part formed on DNA/Ru(bpy)32+ hybrid film and increase in the amount of reactive charge in the aggregated part.</p>
