title: The mechanism of quenching of the lanthanide excited state for optical probes using sensitised emission.
abstract: The mechanism of quenching of the excited state of terbium and europium complexes by electron-rich reductants occurs by formation of an exciplex involving the triplet excited state of the sensitising chromophore.
