[en] The flash photolysis technique was employed to study the properties of eosin triplet state in aqueous micellar solutions. Increasing the concentration of cetyltrimethylammonium bromide from 10−6 M to the CMC leads to a dramatic decrease of triplet absorbance and to the appearance of a very fast decay process of triplet state resulting from the formation of dye-rich induced micelles. From the CMC to 10−2 M, the absorbance and the lifetime of triplet state increase progressively.
