摘要：

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