Abstract

We have presented novel surface plasmon-coupled emission (SPCE) based on solid-state electrochemiluminescence (ECL) of Nafion films containing tris(2,2′-bipyridyl)ruthenium(II). This approach combines the advantages of ECL, efficient emission in the absence of an external light source, with the highly directional emission of SPCE. We described theoretical calculations and optimal Nafion film thickness to get SPCE based on solid-state ECL. We confirmed the SPCE and dose-dependent SPCE response from the concentration range of 0.05-0.5% (w/v) [Ru(bpy)3]2+ in the Nafion film. SPCE based on solid-state ECL can be used as a useful platform for the analysis of chemical and biomolecular interactions.
