  • Electroluminescent electrode made of a tris bipyridyl ruthenium complex embedded in a perfluorinated polymer and deposited on a transparent electrode
    Patent number: 5075172
    Abstract: An electrochemiluminescent layer for use in apparatus for determining the concentration levels of pollutants in water by measuring the increase in light emission of a luminescent surface electrochemically excited by a supporting electrode surface, where a tris bipyridyl ruthenium complex forms a homogeneous mixture with a perfluorinated, sulfonated polymer film, deposited on a transparent, electrically conductive surface, in which case the surface may also have a fine-grained structure.
