Pyrene sensitized phosphorescence enhanced by the heavy atom effect in thewater-heptane-sodium dodecyl sulfate-pentanol microemulsion

The influence of the external TI+ "heavy" ion on the singlet and triplet ex cited states of the pyrene and Trypaflavine molecules solubilized in the wa ter-heptane-sodium dodecyl sulfate-pentanol microemulsion was studied. The triplet-triplet (T-T) energy transfer in the system Trypaflavine (donor)-py rene (acceptor) and the sensitized phosphoresce rice of pyrene were first o bserved in the microemulsion containing TI+ ions. The quenching rate consta nts of the excited states of the luminophores by TI+ ions were calculated.
