Demonstration of surface plasmon-coupled emission using solid-state electrochemiluminescence

► SPCE emission under ECL process was measured for potentials of 0.9, 1.0 and 1.1 V. ► SPCE emission peaks around ±74.5° were successfully observed at 1.1 V. ► The peak angle and the potential were consistent with SPR experiments and ECL behavior of the [Ru(bpy)3]2+-Nafion film.
