Abstract
A laser-induced fluorescence investigation of the phenothiazine dyes Methyl ene Blue (MB) and Methylene Green (MG(+)) is reported. To study the effect of environment, fluorescence spectra of these molecules in a variety of sol vents with different polarity and various concentrations of an anionic surf actant were measured. The polarization and anisotropy analysis showed that there is no abrupt behavior except at the surfactant concentrations corresp onding to the critical micellar concentration.
