Abstract

The influence of the external TI+ “heavy” ion on the singlet and triplet excited states of the pyrene and Trypaflavine molecules solubilized in the water-heptane-sodium dodecyl sulfate-pentanol microemulsion was studied. The triplet-triplet (T-T) energy transfer in the system Trypaflavine (donor)-pyrene (acceptor) and the sensitized phosphorescence of pyrene were first observed in the microemulsion containg Tl+ ions. The quenching rate constants of the excited states of the luminophores by Tl+ ions were calculated.
