Visual electrochemiluminescence from an all-solid-state electrochemical cell.

Visual electrochemiluminescence (ECL) emission from L012 and hydrogen peroxide is generated from an all-solid-state electrochemical cell with a polyacrylamide hydrogel as the solid electrolyte. The emission is strong enough to be visualized with the naked eye, which offers a new idea for the design of an all-solid-state ECL based sensor in air.
